camshaft Reply #1 – June 15, 2006, 11:55:09 PM roller and flat tappet camshafts are totally diffrent. I am not sure if you can run an old one with a newer roller rockers. I would assume that you would want to. Quote Selected
camshaft Reply #2 – June 15, 2006, 11:58:01 PM From what I had picked up when trying to find a cam for my car you can't inter mix roller and flat tappet cams and lifters. From what I understood the cams are different strengths of meterial so you would destroy either the lifters of the cam. Quote Selected
