Description Technical Specs Extended Information
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
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 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!
