After x pipe....

It ran perfect before the Xpipe. Was tuned by the engine builder on the Dyno. Cam is a custom grind, let me find the post

I did have to do some re tuning when I got it home, at sea level, was 1200 ft above sea level at dyno. But got it running perfect.

I just wanna check something. Are you sure that cam card is correct?

Cause I'm seeing a cam with a 102 lobe separation. 247/250 duration at 50. That is a serious cam for a small block. Even a 408 cube small block. Power with a cam like that wouldn't come on until at least 3,000 rpm. Maybe higher? What is this in? I'm also surprised at his recommended stall...

If the cam card is correct then I also have to disagree with moper. A 1000-1200 rpm idle seems in place for a cam like this. Looks a lot like a circle track cam.
