390 FE

The 390 in³ (6.4 L) engine was a popular high-performance engine; although not as powerful as the 427 and 428 models, it provided good performance, particularly in the lighter weight vehicles.

351 Cleveland

The 351 Cleveland was introduced in 1970 as Ford's new muscle car engine. It was built through the end of the 1974 model year. It incorporated elements learned on the Ford 385 engine series and on the Ford Boss 302 engine, particularly the poly-angle combustion chambers with canted valves and the thin-wall casting technology. Both a 4V (4-barrel carburetor) performance version and a 2V (2-barrel carburetor) basic version were built. The latter had a cylinder head with smaller valves to suit its intended applications. The 351 Cleveland was produced through the 1974 model year, when Ford decided to economize and use the same block for both 351 and 400 cubic inch (5.8 and 6.6 L) applications.

5.0

The 5.0 was actually a 302 in³ (4949 cc) engine updated with the metric naming convention of the 1980s. This engine powered many rear wheel drive Ford cars, including the Crown Victoria and Mustang. It was replaced by the 4.6 L Ford Modular engine in the early 1990s.

Applications:

• 1988-1992 Lincoln Continental Mark VII, 225 hp
• 1990 Lincoln Town Car, 150 hp
• 1998-2001 Ford Explorer

The last 5.0 L engine was produced at Cleveland Engine Plant #1 in December 2000, as part of a build ahead to supply Ford of Australia. They installed their last 5.0 L engine in a new vehicle in August 2002.

351W

The 351 Windsor featured an even longer stroke thanks to a taller deck. It produced 250 hp (186 kW) with a 2 barrel carb or 290 hp (216 kW) with a 4 barrel. There were many other changes to this engine, including the intake, heads, rods, and firing order. Though the engine family is the same as the 289 and 302, and employs the same bell housing and head interchange as well as a few other small parts, the block itself is different. The block is taller and wider than other windsor small blocks, with larger main caps and thicker connecting rods. Also the distributor is slightly different to accommodate a larger oil pump shaft and larger oil pump.

The 351W was introduced for the 1969 year model rated at 250 hp (186 kW) with 2 barrel carb or 290 hp (216 kW) with a 4 barrel. The four barrel version actually produced 320 to 325 hp (239 to 242 kW). Though the 351 Cleveland was given higher power ratings, the 351W can be modified to run the same level of performance. The reduced performance was due to rather restricted airflow in the cylinder heads (the Cleveland heads were larger).

The 351W was produced from 1969 to 1996. It was installed in everything from Mustangs to the fullsize cars, and all the way up to the F350. It has been one of Ford's most successful motors.

302 Windsor

A stroked Windsor, at 302 in³ (4.9 L), was introduced in 1968. This engine was used in various Ford cars and trucks through early 2001. There were 2 and 4 barrel versions of this engine, and the 1968 Shelby GT350 used this engine. For 1968 only a special very high performance version of the 302 was also produced. Its main features included an angled cast iron high rise intake manifold and large port cast iron exhaust manifolds. The block was a high strength, high nickel content "hecho en Mexico" design with larger 2-bolt main caps. The heads were similar to the 289 HiPO K-code's with small, close tolerance pushrod holes. Emissions standards reduced the output of the 302 to just 140 hp (104 kW) in 1975, but modern technology brought the power back in the 1980s. Throttle body fuel injection first appeared on the Lincoln Continental in 1980, and was made standard on all applications in 1983. Electronic sequential fuel injection came in 1986.

The 302 was also offered for marine applications in both standard and reverse rotation setups.

Boss 302

The Boss 302 engine is a racing small-block V8 from Ford Motor Company. It was a hybrid of two small-block Ford V8s - It used the block of the small Ford Windsor engine and the heads of the larger Ford Cleveland engine. It was created for the SCCA's Trans-Am road racing series, and was fitted to the Boss 302 Mustang.

The high nickel content block has a thicker deck, cylinder walls and beefy 4-bolt main caps. It is easily identified by screw in freeze plugs on the side of the block, pent roof valve covers, very wide heads and a very wide intake manifold. The connecting rods are heavy, high strength steel forgings made for high rpm use. The crankshaft is a cross drilled high strength steel forging. The cam and lifters are high lift solid mechanical units.

The unique, wide, large port Cleveland style 4V heads with poly angle, semi-hemi style valve placement are what give the Boss 302 its unique high power capabilities. Early units were typically characterized by very large intake and exhaust valves sitting in a small quench style combustion chamber. Huge intake ports made certain that the engine only "woke up" above 4000 rpm. At racing speed the engine's performance was quite remarkable especially in the upper rpm ranges.

289 Windsor Engine

The 289 in³ (4.7 L) Windsor was also introduced in 1963. It featured a 4 inch (102 mm) bore, the same as all future Windsors, and larger valves. This version was used in the Ford Mustang. With a 2-barrel carburetor, the 289 put out 195 hp (145 kW), but 225 hp (168 kW) was possible with a 4-barrel. Early versions prior to 1967 had a 5 bolt bellhousing pattern that was different than later 6 bolt units.

Applications:
1966-1967 Sunbeam Tiger

The Windsor engine is a 90-degree small-block V8 from Ford Motor Company. It was introduced in 1962, replacing the old Ford Y-block engine. Though not all of the engines in this family were produced at the Windsor, Ontario engine plant, the name stuck. It was replaced in 1995 with Ford's new 4.6 L modular V8 engine.

Looking ahead

Ford continues to sell about 150,000 Mustangs annually. And, many view the 1964-1973 models as American automotive icons the equal of the 1955, 1956 and 1957 full-size Chevrolets and the Corvette. Thanks to continued interest in the marque, restoring Mustangs is a popular hobby. Mechanical parts are as close as the corner auto parts store, Ford dealer or wrecking yard with most out-of-production parts available as highly accurate reproductions. Even the very first production Mustang is still around.

Originally purchased new by Stanley Tucker, an airline pilot from St. John's, Newfoundland, Ford Motor Company offered him Mustang number one million in exchange in 1966; he chose a new made-to-order Mustang instead. Number one is currently on display at the Henry Ford Museum in Dearborn and a photo of the car can be viewed at their website.

Today, with its supercharged 4.6-liter, 32-valve, four-cam V8 (underrated at 390 hp) the present SVT Cobra Mustang is the fastest, most powerful factory model in the Mustang's history. The all-new 2005 Mustang GT will come standard with a 300 horsepower (223 kW) single overhead-cam 3 valve modular V8. A supercharged 400+ horsepower (300 kW) Cobra is quite likely for 2006.

With the closure of Rouge assembly plant in Dearborn, Michigan on May 10, 2004, a plant that built Mustangs from the very beginning, production has been moved to the Auto Alliance plant in Flat Rock, Michigan. The last car off the Dearborn line was a bright red 2004 Mustang GT convertible. On hand for the closing ceremonies was the aforementioned first production Mustang, also built at Dearborn.

The New Mustang

At the 2004 North American International Auto Show, Ford introduced a redesigned Mustang for the 2005 model year, with styling inspired by 1960s Mustangs. This car gets Ford's new DC2 platform and will continue the tradition of low cost, rear-wheel drive performance.

The 2005 Mustang GT has a 300 hp (224 kW) 4.6 L 3-valve Modular V8 with variable valve timing. It retains the traditional but controversial live rear axle, and offers improved handling and ride. Modern production facilities and computer aided design have allowed the new Mustang to have 100% more strucutal rigidity over its predecessor, and have greatly increased build quality as well as fit and finish. One particularly interesting feature are the gauges' (speedometer, odometer, etc.) ability to change color as selected by the driver.

"The Boss Is Back"

In 1982, Ford reintroduced a high-performance Mustang GT which opened the door for an entirely new era of the muscle car. Wringing a then-respectable 180 hp (134 kW) from its "5.0" (actually 4.9 L/302 in³) Windsor V8 and backed by a four-speed transmission, aggressive tires and stiff suspension, magazine ads of the period shouted, "The Boss Is Back." This, by the way, was the first of the "5.0" Mustangs, cars that gave birth to an entire aftermarket performance industry and continue to remain extremely popular today. This engine was dropped in favor of the new overhead-cam 4.6 L Modular V8 from the Lincoln Town Car.
In 1994, the Mustang underwent its first major redesign in 14 years. This incorporated some stylistic throwbacks to early Mustangs. The car remained rear-wheel drive. It greatly revived the popularity of the brand. The base model came with a 3.8 L V6 engine and the GT the "5.0" 4.9 L V8. A high performance 240 hp (179 kW) 5.0, larger brakes, and suspension modification was available on the Cobra models. The Mustang was Motor Trend magazine's Car of the Year award for the third time in 1994.

In 1996 the 5.0 engine was replaced by a 215 hp (160 kW) 4.6 L SOHC V8 known as the modular motor. The Cobra version was modified that year with a 305 hp (227 kW) dual over head cam configuration of the 4.6 L V8. Horsepower in the GT was increased to 225 for '97 and '98.

In 1999 the body style was updated and the Mustang GT's horsepower increased to 260, while the Cobra claimed 320 hp. Testing by Car and Driver magazine and numerous buyers contradicted these claims, and Ford was later proved to have misstated the horsepower gains. As a result, the Cobra was not produced in 2000, and the company developed new parts to replace the missing power.

Special Cobra R versions were available, in limited edition, in 1993, 1995, and 2000. Mostly race cars, they were stripped of air conditioning, radios, and back seats. The suspensions were finely tuned. In 1995 and 2000 the Cobra R's had increased displacement engines (5.8 L and 5.4 L, respectively) that made these cars extremely potent track machines.

As electronic engine management and emissions technology developed, so too did performance. The lone remaining 1960s muscle car marques, Mustang, Camaro and Firebird, grew in power and handling better than the cars that preceded them. With production of the Camaro and Firebird ending in 2002, only the Mustang remains as the sole survivor of the ponycar era.
In 2004, Ford produced a special 40th Anniversary Edition of the Mustang. Available in both Standard and GT editions, it consisted of 40th Anniversary badging, special metallic red paint with gold stripes, enhanced interior, and some "special" collectable items for the owner. It also marked the end of this design of the Mustang, as 2005 ushered in an all-new model.

The next generation

Now based on the mid-sized Ford Fairlane/Mercury Comet instead of the compact Falcon, the Mustang grew larger and heavier with each passing year, culminating with the 1971-73 models designed under the supervision of Ford's new product design manager, Seamon "Bunkie" Knudsen, originally of General Motors. Knudsen's turn at the helm would see the last high-performance big-block Mustang, 1971's 375 horsepower (280 kW) 429 Super Cobra Jet. Ironically, that very same body style that was designed for the sole purpose of big-block installation versions were limited to a maximum of 351 in³ (5.6 L) in 1972 and 1973, due almost entirely to extremely strict US emission control regulations. Two more high-performance engines were introduced in 1972, the 351 "HO" and 351 Cobra Jet. Both cars were excellent performers, but at nowhere near the level of the Boss cars and original Cobra Jet. This was more radically different a car than anyone could have imagined in 1964, and Ford was deluged with mail from fans of the original car who demanded that the Mustang be returned to the way it was.

The 1974 introduction of the short-lived Mustang II earned Ford Motor Trend magazine's Car of the Year honors again and actually returned the car to more than a semblance of its 1964 predecessor in size, shape and overall styling. Though Iacocca insisted that the Mustang II be finished to quality standards unheard of in the American auto industry, the II suffered from being not only smaller than the original car, but heavier and slower as well. Available as a hardtop or three-door hatchback, the new car's base engine was a 2.3-liter, overhead-cam four-cylinder, the first fully metric engine built in the US for installation in an American car. A 2.8-liter V6 was the sole optional engine, meaning the popular V8 option would disappear for the first and only time in 1974, and Ford was swamped by buyer mail and criticized in the automotive press for it.

Since the car was never meant to have a V8 in the first place, it became a mad scramble to re-engineer the car in order to reinstate the 302 in³ V8 option in time for the 1975 model year. Like the car that preceded it, the Mustang II had its roots in another compact, the Ford Pinto, though less so than the original car was based on the Falcon. The car sold well, with sales of more than 400,000 units its first year. Despite innovations such as rack-and-pinion steering and a separate engine subframe that greatly decreased noise, vibration and harshness, the Mustang II never caught the public's fancy like the original ten years prior had.

The Arab oil embargo, skyrocketing insurance rates and aforementioned US emissions and safety standards that destroyed the straight-line performance of virtually every car of the period certainly didn't help. Chrysler ended production of the Barracuda and its stablemate, the Dodge Challenger in 1974 and GM nearly discontinued the Camaro and Firebird. But this dark chapter in automotive history would not last. On the momentum of the Mustang II's understated success and under the direction of Ford's new styling chief, Jack Telnack, a totally new Mustang hit the streets in 1979. This "third generation" 1979 model (known as the Fox platform - it was introduced a year earlier as the Ford Fairmont) gives much to its successors for nearly the next 25 years, along with thousands of upgrades, improvements and restyling over that time.

The Mustang grows up

The 1966 Mustang debuted with only moderate trim changes, and a few new options such as an automatic transmission for the "Hi-Po," new interior and exterior colors, an AM/eight-track "Stereosonic" sound system and one of the first AM/FM monaural radios available in any car. The 1967 model year would see the first of Mustang's many major redesigns with the installation of "big-block" V8 engines in mind. The high-performance 289 option now took a supporting role on the option sheet behind a massive 320 horsepower (239 kW), 390 in³ (6.4 L) four-barrel engine direct from the Thunderbird. A drag racer for the street bowed during the middle of the 1968 model year as the 428 Cobra Jet (7 L), underrated at 335 horsepower (250 kW). 1969 saw the introduction of both the car's third body style and a handbuilt muscle car intended solely to satisfy the homologation rules of NASCAR, the Boss 429.

Available in 1969 and 1970 only, and looking like a standard Mustang SportsRoof (the new corporate name for the fastback) with the new Mach 1 musclecar version's deluxe interior, the Boss 429 sported none of the garish decals and paint schemes of the day. Only a hood scoop, 15 inch (380 mm) "Magnum 500" wheels with Goodyear "Polyglas" tires and a small "BOSS 429" decal on each front fender (see photo) hinted that the largest and, in racing trim, most powerful Ford V8 of all time was fitted under the hood. Intentionally underrated for advantages both in racing as well as insurability at 375 horsepower (280 kW) and 450 foot-pounds (610 Nm) of torque even with racing touches straight from the factory such as aluminum heads with hemispherical combustion chambers and a combination of O-rings and seals in place of head gaskets, it was believed that yet another 75 to 100 horsepower (50 to 75 kW) was on tap once the single four-barrel carburetor and intake, restrictive factory exhaust system and engine speed governor were replaced or removed. While power steering was a "mandatory option" on the Boss 429, neither an automatic transmission nor air conditioning were available. In the case of the latter, there simply wasn't enough room under the hood!

Also available during that two-year period was another homologation special for the up-and-coming sport of Trans-American sedan racing. The Boss 302 was Ford's attempt to mix the power of a musclecar with the handling prowess of a sports car. The automotive press gushed over the result, deeming it the car "the GT-350 should have been." Boasting a graphic scheme penned by Ford designer Larry Shinoda, the "Baby Boss" was powered by an engine that was essentially a combination of the new-for-1968 302 in³ (4.9 L) V8 and topped with cylinder heads from the new-for-1969 351 in³ (5.8 L) "Cleveland." This combination meant that the Boss 302 was good for 290 horsepower (216 kW) through its four-speed manual transmission. Ford originally intended to call the car Trans Am, but Pontiac had beaten them to it, applying the name to a special version of the Firebird.

The Industry Reacts

In its first two years of production, three Ford Motor Company plants in San Jose, Dearborn and Metuchen, New Jersey produced nearly 1.5 million Mustangs, a sales record unequalled before or since. It was a success that left General Motors utterly flat-footed and Chrysler Corporation only slightly less so. Chrysler, more or less accidentally, had just introduced a car that could be considered a competitor, the Plymouth Barracuda. Though the "'Cuda" would grow into one of the most revered muscle cars of all time, it started out as an act of desperation and was not much more at first than a compact Plymouth Valiant with a hastily grafted fastback rear window. As for GM, they were certain that they had a Mustang fighter in their rear-engined Corvair Monza, but the sales figures didn't even come close. The Monza was a fine performer, but was only a six-cylinder compared to the Mustang's available eight-cylinder. It took GM until the 1967 model year to counter with the Chevrolet Camaro and Pontiac Firebird. Even Lincoln-Mercury joined the fray in 1967 with the introduction of an "upmarket Mustang" (and subsequent Motor Trend Car of the Year), the Mercury Cougar, using the name originally given to the Mustang during the development phase. In 1968 American Motors (AMC) would introduce the Javelin and later, the 2-seater, high-performance AMX. This genre of small, sporty and often powerful automobiles was unofficially dubbed the "ponycar" as a tribute to the car that started it all.

From sporty car to sports car

Some major changes to the Mustang occurred at the start of 1965 model year production, a mere five months after its introduction. First was an almost complete change to the engine lineup. The 170 in³ (2.8 L) I-6 engine made way for a new 200 in³ (3.2 L) version. Production of the 260 in³ (4.2 L) engine ended with the close of the 1964 model year with a new, 200 horsepower (149 kW), two-barrel 289 in³ (4.7 L) taking its place as the base V8. A 225 horsepower (168 kW), four-barrel 289 in³ was next in line followed by the unchanged "Hi-Po." The DC generator was replaced by a new AC alternator on all Fords and the now-famous Mustang GT was introduced, available with either four-barrel engine and any body style. Originally, the Mustang was available as either a hardtop or convertible. During the car's early design phases, however, a fastback model was strongly considered. When the 1965 model year production began in September, 1964, the Mustang 2+2 fastback, with its swept-back rear glass and distinctive ventilation louvers made its debut as well.

This was the body style that car builder and former race driver Carroll Shelby would convert, with Ford Motor Company's blessing, into a special model designed with only two things in mind, namely winning races and beating Chevrolet's Corvette. Designated simply as "GT-350", these purpose-built performance cars started as "Wimbledon White" fastbacks with black interiors shipped from the San Jose, California assembly plant and fitted with the 271 horsepower (202 kW) V8, four-speed manual transmission and front disc brakes but less the hood, rear seat and identifying trim. These few cars were converted to street, road racing and drag trim in Shelby's plant at Los Angeles International Airport.

Modifications to both the street and racing versions included a side-exiting exhaust, Shelby 15 inch (380 mm) magnesium wheels (though some early cars were fitted with the steel wheels they were shipped with), fiberglass hood with functional scoop, relocated front control arms to reduce understeer and neutralize handling, quicker steering, Koni shock absorbers, a limited slip "Detroit Locker" rear end with Ford Galaxie drum brakes, metallic brake linings at all four corners, rear-mounted battery, rear anti-sway bar with beefed-up front anti-sway bar, dash-mounted gauges, a fiberglass parcel shelf and spare tire holder where the rear seat was intended to be and considerable engine work, boosting output to 306 horsepower (228 kW).

Even the car's basic body structure was stiffened up front with an angled brace intended for the export models and so-called "Monte Carlo" bar triangulating the underhood shock absorber towers. Though Shelby's influence on the car diminished as Ford's influence grew, the 1965-1970 GT-350 and its big-block brother, the 1967-1970 GT-500 are among the most highly sought-after automobiles in the world. So too are the high-performance models offered over the years by other automotive tuners following in Shelby's footsteps...see the "Mustang Club of America" link at the bottom of the page to learn more.

Coming to market

The timing of the car's introduction coincided perfectly with the first wave of the postwar "baby boom" which was heading off to work in a strong economy. Incredibly, no domestic manufacturer up until that time had anything remotely resembling an affordable yet youthful and sophisticated automobile aimed at this burgeoning market, and Iacocca knew it. Despite his repeated attempts to receive the go-ahead to produce such a car, his proposals fell on mostly deaf ears. Because the company was still smarting financially after the demise of the Edsel Division in late 1959, upper management at Ford under Robert McNamara (later United States Secretary of Defense under Lyndon Johnson) wasn't willing to take such a major risk.

Still, Iacocca persevered and was given the green light to produce the Mustang in mid-1962, which gave the design team only eighteen months to design and develop the car. Not only did the project wrap up in under eighteen months, it wrapped up under budget as well thanks to the decision to use as many existing mechanical parts as possible. As far as the design itself was concerned, Ford stylists basically threw out the company handbook on design limitations, pushing the stamping technology of the time to its limit in such design areas as the sweep of the rear lower valence and the remarkably complicated front end stampings and castings. Curved side glass was used as well, but at a price since the technology to produce distortion-free curved safety glass was still fairly young. And though most of the mechanical parts were directly taken from the Falcon, the Mustang's body shell was completely different from the Falcon's, sporting a longer wheelbase, wider track, lower seating position and overall height and an industry first: The "torque box." This was an innovative structural system that greatly stiffened the Mustang's unitized body construction and helped contribute to its excellent handling, at least compared to other cars of the time.

Built to order

For such an affordable car, the Mustang had an enormous list of options ranging from a tissue holder to an automatic transmission all the way up to three separate V8 options. First was a 164 horsepower (122 kW), 260 in³ (4.2 L) version with two-barrel carburetor based on the 221 in³ (3.6 L) "Fairlane" engine introduced in 1962. A 210 horsepower (157 kW), 289 in³ (4.7 L) version with four-barrel carburetion was the middle choice with the top-of-the-line engine being a thundering 271 horsepower (202 kW), 289 in³ engine with a four-barrel carburetor and solid-lifter valvetrain. At a cost of nearly $700, this high-performance 289, or "Hi-Po" as it came to be nicknamed, was the single most expensive option available on the Mustang. The option list added to the car's popularity since it could be ordered from "mild to wild," depending on the buyer's taste and budget. The most popular drivetrain combination in the car's first two years would prove to be a 200 horsepower (149 kW), two-barrel "Challenger" version of the 289 introduced at the start of the 1965 model year backed by a three-speed "Cruise-O-Matic" automatic transmission.

Accolades

Championed by Ford Division general manager Lee Iacocca first as a two-seat mid engined roadster then later as a four-place car and penned by David Ash and Joseph Oros in Ford's Lincoln-Mercury Division design studios (theirs was the winning design in an intramural design contest called by Iacocca), the base, yet well-equipped Mustang hardtop with its 105 horsepower (78 kW), 170 in³ (2.8 L) inline six-cylinder engine and three-speed manual transmission listed for US$2,368. Looking like a car that cost hundreds of dollars more with its "long hood/short deck" styling reminiscent of designs such as the Lincoln Continental and two seat Ford Thunderbird with an intentional touch of Ferrari at the grille, the Mustang earned a number of prestigious auto industry awards and accolades its first year including Motor Trend Car of the Year, pace car duties for the 1964 Indianapolis 500 and the Tiffany Design Award for "excellence in design," the first automobile so honored.

A Bit of History

The Ford Mustang is a popular compact car. It was originally based on the Ford Falcon. The first production Ford Mustang, a white convertible with black interior, rolled off the assembly line in Dearborn, Michigan on March 9, 1964 and was later introduced to the North American public as a "1964 1/2" model both at the New York World's Fair on April 17, 1964 and via all three American television networks on April 19 that year by the Ford Motor Company. It was the most successful product launch in automotive history, setting off near-pandemonium at Ford dealers across the continent. The original Mustang is considered to be the first pony car, and inspired many imitators.
