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.
