Everybody,
What do you guys think the CR of a 454 with a standard FelPro head gasket, flat top pistons, & vortec heads with a 100cc would be?? I have seen the online calculators, but I do not know the answers to all the variables. Here are the specs on the engine: 454 bored .040 over, flat top pistons, vortec heads with the stock valves (2.06 / 1.72), 280 comp cam, (specs link below), roller tip rockers, Edelbrock RPM Air Gap intake & Holley 750cfm carb. Below are the links for the cam & CR.
Thanks,
Chris
