Fits On/Installation Notes:
The DIY foundation for big torque!
Its simple: We offer the ZZ502/502 Base crate engine for the builder
who wants the super-strong bottom end and high-flow aluminum
oval-port cylinder heads, but also wants to finish the engine their way.
The ZZ502/502 Base Engine uses our new cylinder block casting that is
stronger and better suited to high-performance combinations. A forged
steel crankshaft, forged rods and forged pistons form the reciprocating
assembly, with a smooth-operating hydraulic roller camshaft delivering
big 0.527/0.544-inch lift. The lightweight aluminum heads boast 110cc
combustion chambers and big, 2.25-inch intake and 1.88-inch
exhaust valves.
We rate the ZZ502/502 Base engine at 502 horsepower and 567 lb.-ft.
of torque when it is finished with GMPP aluminum intake manifold P/N
12363406 and Holley 870-cfm carburetor P/N 19170094. The other parts
you need to complete the engine including chrome dress-up parts
are available from your GMPP dealer and gmperformanceparts.com.
The ZZ502/502 Base is a great foundation. Its up to you to make the
most of it.
