Here are the TP boxes that are 4 boltI knew the original owner had changed the cam but all I knew was that he had put in a "mild" cam, which I didn't assume the .600 to be a "mild" cam. tx - you're absolutely right...it is not a straight comparison of one cam against another because of the jug work. It was good to hear he had also put rollers in, although I think they are still the TP rocker boxes.
