Delivered complete from the oil pan to the intake manifold a"including an HEI distributor a"the 350/350 racing engine has the proven parts and horsepower to enable a competitive racecar. GM Performance Part's Fast Burn cylinder heads are the fast way to the winner's circle a"and they're standard on the 350/400 Late Model GM racing engine from GM Performance Parts. This brand-new, factory-sealed racing engine includes a racing-only 8-quart circle track oil pan, with dual kick-out design, along with a valve cover breather kit and special "kool nut" rocker arm design. The assembly also includes an open-plenum high-rise intake manifold and 1.5:1-ratio aluminum roller rockers.
