    Without trying several cams and trying them you are souly going off his guessing on what would work the best.
    Alot of his cams are tweaked OTS. CAMS
    excellent point George. Ya there are a few other people that I will talk to for my next cam. Kurt Urban or some of the guys off the bullet.

    Thanks George. What is the overlap on a TR224 with a 112 lsa?

    Nvm. Found a calculator. Its 0 degrees overlap. It seems to me that a TR224 on a 112 lsa would be the perfect cam for my setup BC of the fact it has no overlap, relatively low lift which is good with my stock heads BC I'm sure they don't flow much past .570 anyway, 112 lsa will move the power band down lower so I don't have to Rev to 7000 and 224 seems like a good amount of duration for a Turbo 5.3

    I think the duration on the cam in Mitch's truck is 224/224 and he put down over 700 on a stock 5.3 with twins. Lots more lift though I think
