With the heart of the proven, durable ZZ4 crate engine, the 350/355 limited late model factory-sealed racing engine has all the power to keep you at the front of the pack for Saturday night's feature race. The 350/355 is rated at 355 horsepower and 405 lb-ft of torque and has all the tough basics of the ZZ4 street engine, including a forged steel crankshaft, high-silicon aluminum pistons, hydraulic roller camshaft and lifters, and aluminum cylinder heads. The high-performance head feature D-shaped exhaust ports and high-velocity intake runners to promote fast and unobstructed flow through the engine, providing great high-rpm performance on the racetrack. An 8-quart circle track oil pan, with dual kick-out design, handles the oil storage, along with a valve cover breather kit and special "kool nut" rocker arm design. The assembly also includes a dual-plane high-rise intake manifold, HEI distributor and cast iron water pump. Add your carburetor, starter and exhaust and don't forget to thank GMPP when giving your winner's interview. Installation notes: Requires addition of carburetor, starter, plug wires 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. Racer's Note: The 350/355 Limited Late Model racing engine is factory-sealed at the intake manifold, cylinder head, front cover and oil pan wit special GM bolts. The 355 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-octane gasoline.
