small block cams

Hipo65, thanks for the advice, yeah im not expecting a whole bunch out of it at this point, I just wanna be able to play with it some this summer and then hopefully next winter do a fresh engine build or swap, Im spending this winter doing some interior work so im running out of time and definitely money before spring hits. just want it sound nice for cruising and have a little more power, love the thump. it has what looks like (haven't measured it) 2.5" exhaust and welded mufflers on it but the guy I got it from had a failed attempt at a header install so it has little tiny twisted up head pipes coming off factory manifolds welded into the 2.5" pipes so that's gotta go.
