Does anybody know what kind of vacuum this will produce for an otherwise stock 302. I'm getting between 9 and 10 and wondered if that's normal. I thought it was supposed to have more than that. Trying to make sure on the power valves I need.

I have no idea how that Comp cam is supposed to compare to the stock "30-30" cam, but 9"-10" Hg. at 900 rpm is as good as it gets with the "30-30".

Ok, thanks. I put in 4.5 power valves.
