Re: Cam suggestions?
Those are decent cams, but the vortecs will really wake up with a dual pattern cam. The voodoo line is decent. It has really steep intake ramps, and slow exhaust ramps. They are not the only split patterns out there, though. And they do have pretty wide LSA's.
I think you're right in the ballpark with your numbers, adv. duration, duration at .050". Unless those heads have been clearanced/machined for more lift, I think you need to stay around .450".
Bottom line...you need a split pattern, in the 262 to 274 range.
