HP gains with bigger lift cam??????

I'm looking for the short general answer here....

I've got a 14 : 1 compression 470 inch solid roller BBC...My current cam has a net lift of .650 with a 280 dur @ .050 110LSA. Timing locked out at 38 Deg. 1050 dommie

I am in Colorado, so air is thin.

For a quick answer.......would I gain more or less than 30 HP at 7500RPM with a .700 lift cam?

Thanks,


A...........

As mentioned...heads are key factor AND are the two cams going to be comparable otherwise?

But for a quick reference, I just did a 555" with Dart CNC 335's. Going from a .696" (1.8 rockers) 270* flat tappet...to a .788" lift 268* solid roller barely picked up 30 or so HP.
