Fits On/Installation Notes:

GM Performance Part\'s Fast Burn cylinder heads are the fast way to the winner\'s circle and they\'re standard on the 350/400 Late Model GM racing engine from GM Performance Parts. This brand-new, factory-sealed racing engine is based on the popular Fast Burn 385-horsepower street crate engine, but 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. Because it\'s based on the 350 Fast Burn engine, the 350/400 racing engine includes a bulletproof bottom end, anchored by a forged steel crankshaft and hypereutectic pistons. The 23 degree, Fast Burn aluminum heads enable tremendous power in the small-block V-8 because of a unique chamber design that quickly and completely burns all of the air/fuel mixture giving you maximum power all the time.
