COMPRESSION QUESTION?
About what compression will I have with a stock L98 short block and stock Corvette aluminum heads. Also thinking about running a ZZ4 camshaft with a Performer RPM. What kind of HP #s should this combo have. (350hp?) Can I still run pump gas?
Thanks Frank

CR will be about 10:1. HP should be in the 350 range with the ZZ4 cam and good exhaust on pump gas.
What is a ZZ4? A 4-bolt main 350 with Corvette aluminum heads, roller cam, Performer-like intake manifold. With 650 CFM carb and headers, it makes 355 HP. The RPM manifold should only help.
