I went to the track last night and did horrible which is weird. I usually run 13.4 and 13.5 all night but last night I barely could get a 14.8 and I did the same things I always do when I drive. On one run when I launched I hit this flat spot that has never happened before from 3000-4500rpm before it picked up and started moving again. Do I have soe kind of timing isusses I should check or could I just have to much carb for the truck? :bang:

What CFM Carb are you running, and is it the same one you've always ran? And have you checked your plugs?

fuel filter?

Its approx. a 750cfm. The same carb I have always run. The truck made 370rwhp and 385rwtq. I do have a replacement Barry Grant Filter. So change the filter huh? Could I possibly still have timing issues and what about too high of a fuel pressure setting?

Huh, that's weird. Check your fuel filter and plugs first, knock the easy stuff out of the way.

So where should I go after if that doesnt help anything

It really sounds like either a fuel issue or spark issue to me. I would *think* if it was a timing issue, you'd just run like shit all the time rather than just certain RPM's.
