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, hypereutectic pistons, steel hydraulic roller camshaft and aluminum cylinder heads. The high-performance ZZ4 heads 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 nut design. The assembly also includes a dual-plane high-rise intake manifold, HEI distributor and cast iron water pump.
