Only slightly off topic.
Jerry, are you using the comp cams 12-107-3 camshaft in stock z28 builds? Do you consider it a dead on match for the original 30 30?
I know JohnZ recommends the Federal Mogul. Quote: "Don't know offhand if the Comp cam is a dead-on duplicate or not, but the Federal-Mogul/Speed-Pro/Sealed Power cam is - their #CS-118R (cam only) or #KC-118R (cam and lifters)."
One more questions, as I am getting ready to put together a couple 302's: what valve springs are you using? Thanks.
