Thread: Needing dyno run data with XP cam

Just like it says. Just wantint to be sure where the power end is in the upper rpm range. I know it feels like it stopps pulling in the 6300-6500 range but just want be sure.

C-mon.....Somebody's got to have something. Maybe i'll just have to pay a hundred bucks and get on the dyno my self. It's been on the to do list anyway.

I think you just answered your own question. LOL

I am running the XP cam in my Cutlass and rev to the 6700-6800 mark with it but I also have very agressively ported heads which really help the top end. Most of the stock headed cars that I have put XP cams in seem to pull good to the 6300ish mark and I set the shift points at about 6350-6450 but every car and combo responds differently. In our old 95 prix with an L67 I had a VS cam and ported heads and its peak HP on the dyno was 5800 rpm while most stock cammed cars with rockers peaked about 5300-5400 rpm

Yeah the 6300 mark is what i was feeling. So thanks for the input
