Paladin06

The 426 Hemi was produced for consumer automobiles from 1965 through 1971, and new crate engines and parts are available today from Chrysler. There were many differences between the Hemi and the Wedge-head big-block, including cross-bolting and a different head bolt pattern. The street Hemi version was rated at 425 hp (317 kW) with two Carter AFB carburetors though in actual dyno testing, it made 315 rear-wheel HP in purely stock form which would be approximately 360 gross HP at the flywheel using generally accepted conversion formulas. The engine could produce much higher HP figures with relatively few modifications, but those modifications drastically affected the engine's drivability on the street as they usually were made to take advantage of the free-breathing nature of the heads at high rpms.
