Thanks Deuce, that's good info to know. I went with the 268H, and when it arrived, the cam card actually showed 219 dur @ .050. I ran all the specs on the Comp Cams CamQuest simulator, and it showed 259hp at 5000, and 297tq at 4000. So that's really close to what you came up with. Thanks for running the numbers on your end.
One other decision I'm wondering about now is between the Offy intake and the Clifford intake. Any thoughts on those?
