Valve Float Ok i have a Stock Cube LS1(5.7) carb set up it has
Vic jr intake
Trickflow 225 heads
Yella Tera Rockers
23x/23X comp cam
Gm lifters (GM Performace Part #12499225)
Problem is that if i shift anywere about 6200 RPM's the car slows down. Its like i can feel the power fall off. Anyone had any problems like this or know what to look at first. Heads, Cam, and lifters are only about 3 months old.

I have one more race this year and thats what i am going to do. After this race im pulling motor to freshin it up and check everything.
Its a new pro systems carb with 76/86 jets.
LOL thats what i have been doing. Its the springs that came on the heads. I dont think they have enough open pressure for my cam with the YT rockers.
