had to go back onto dippy.org to look at my old posts to remember what I had for a cam. pretty sure I used their HR259/316 lobe on the intake (259 adv duration, 208@.050", 127@.2" .316" lobe lift for .506 with magnum rockers) and I think the HR265/320 (265 adv/212@.050", 131@.2", .32 lobe lift/.512 with magnum rockers) ground on the factory cam's 112 LSA, installed at like 106-108....man that was a nice running and peppy motor. idled nice at 800 RPM with like 15+" vaccuum, pulled great to 5500+....
