I appreciate all the advise I get here, I really do. I will give that more thought as I am not familiar with that tool. I have never cared for these heads I’m using. They should make power similar to a good Indy head, but they don’t and this cam I bought I’m now thinking it might be a bit too big for my combo. I think something like the cam Andy used in his 470 build a while might work a little better. Think it was a 264/268? I have time to think.
