What's the rest of the cam specs? Duration, both adv. and at .050 is what you need. And the c/r is determined by the pistons and head chamber size, along with a couple other things, so if you dont know what heads you're using, how can you know the 9.7 c/r?? Do you mean that's where you WANT to be?? Post the rest of the cam specs here, and the specific model number....that does sound big just based on the lift. You dont want a big cam in a street car, it sounds nasty, but will dissapoint you performance wise.
