Run up front with our race-winning 400-horsepower 350 with Fast Burn heads!
GM Performance Part’s Fast Burn cylinder heads are the fast way to the winner’s circle - and they’re standard on the CT 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 CT 400 racing engine includes a bulletproof bottom end, anchored by a forged steel crankshaft and hypereutectic pistons. The 23° Fast Burn aluminum heads enable tremendous power in the small-block V8 because of a unique chamber design that quickly and completely burns the air/fuel mixture - giving you maximum power.
With the CT 400 racing engine under the hood of your Late Model, you’ll put a "fast burn" on the competition.
