Crate Engine Circle Track 350/400. Highlights: HP: 400 @5500rpm TQ: 400 @4500rpm Late-style block with one-piece rear main set and 4-bolt main caps Aluminum cylinder heads P/N 12464298 Hydraulic roller camshaft 9.6:1 compression ratio Aluminum competition-style high-rise open-plenum intake manifold 8-quart circle track oil pan Valve cover breather kit Stamped steel center-bolt valve covers Run up front with our race-winning 400-horsepower 350 with Fast Burn heads. GMPP's Fast Burn cylinder heads are the fast way to the winner's circle - and they're standard on the 350/400 limited late model GM racing engine from GMPP. 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 high-silicone aluminum pistons. The 23-degree , CNC-ported 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. With the 350/400 racing engine under the hood of your late model, you'll put a "fast burn" on the competition. Installation Notes: Requires addition of carburetor, starter, ignition, plug wires, water pump and exhaust system (not included). Requires an externally balanced flywheel (not included). The 8-quart circle track oil pan is 7 inches deep at the sump. It will clear most GM rear steer chassis with stock engine location. Racers Note: The 350/400 Limited Late Model racing engine is factory-sealed at the intake manifold, cylinder head, front cover and oil pan with special GM bolts. The 400 horsepower rating was achieved with a Holley 650-cfm four-barrel carburetor, Holley P/N 0-80541-1, 32-inch long by 1-5/8 inch into 1-3/4 inch stepped headers with three-inch collectors, and 92-octne gasoline.
