Hi Duece,
I was thinking this would be a decent motor as long as I can get the cam dialed in. I am going to measure the CC of the heads I have, but what would you recommend for a cam? Just because of price, I was thinking of the Comp Cams 280h or 292h magnum. But I really want a nice roller cam. How much difference in performance and durability will a roller provide over a flat tappet cam. Obviously there is a huge price difference, but I've seen plenty of people make good power with flat tappet cams.

Either way I'm of a 232 or 242 duration with a .5-.510" lift for a flat tappet or .54-.56 lift for the roller. I have a nice set of 1.54" dual springs with dampers so they should be fine anything under .6" lift.
