Cam selection help please
Using all the info you just provided, I got 8.867 on the United Engine calculator. But I also used .020 for a compressed thickness. I THINK those steel shims go a little thinner than that, but I am not sure. That would probably put it right on top of 9:1. If it's got at least the 8.8, I am still thinkin the xtreme high lift will help.....you said you wanted a little more rumble, and it will provide that. It will also produce some more power......provided the compression is there.
