Good Street 5.9 Magnum Cams for Stock Bottom End and Heads

If you want to push it you could even go aggressive as the 380hp crate magnum cam that dyno's 400+ hp, anywhere between stock and that you can go it's really up to you what you want.

"The roller is a fairly stout stick, with a long .288 intake, .292 exhaust duration, and .501/.513 lift-much more than any production small-block." Something like 230/236 @ 0.050" 108 lsa

The crate cam could use more gear and stall, I run mine with 2.xx gears and 2,800 rpm and works ok.
