MFI and engine cam compatibility
I read a post, ,maybe here about engine cam compatibility to MFI as in more modern cams don't work that well with MFI. Not understanding cam design, I don't know What happens with lobe contour, degrees of spread between lobes, etc that separates new tech from old tech. I have a 3.0, 12-1, slide valve, with what I understand is an old grind and it is a rocket. Also a 3.0, 11-1 with bored 2.2 mag stacks with a ''modern cam'', and it is soft, very little snap. I realize not apples to apples, but I had to tune its pump to make it work. Prior I could swap pumps from one engine to another, (both had old style cams at the time) with the tune I had performed on the bench, and no tuning required. Will appreciate any feed back on this subject. Bob
