This cam has more lift, but will help keep the power more in the mid range. Not to radical. You will need to upgrade the valve springs as the stock ones will only support up to .450 lift as this cam is at .474.

A 600 with the mod and jetted down would work nicely for that application. Lotta guys are gonna say 390, but it's a rip off unless you can find a good rebuildable one.
