Car not running what is should, need help.

I ended up with 76 primary and 84 secondary jets. 6.5 power valve and 31 squirters. I tried a 35 squirter in front and it seemed to like it. Yes I checked to make sure throttle was opening all the way. I left on the exhaust this time it is 2 1/4 exhaust and flowmasters. The timing is all in by 2500 rpm. The tire size is 235/60-15, they are 27 inches tall. Not sure how much the rpms drop off after shifting, I think it is around 4000 or so.
