I bought a 79 with a .030 + 400 (406) SBC in it.
I can tell by the idle that it has a mild cam in it but I have no idea about the specs.
By the numbers on the heads I can tell the are from a 400 SBC.
I have no idea what kind of pistons are installed. (Flat top , Domed )
My question is this.
If I want to change to a cam with a more lift how do I make sure it's not going to be too much and cause piston to valve interference ?
