Hey, I have a 1997 Trans am ws6. M6 with 3.42, edelbrock shortys, 3inch flowmaster american thunder,52mm TB,160 therm. Hypertech PPIII(junk).
As of thursday night i am running 13.92@100.2 with a 2.06 60ft.

I am adding roller tip rockers,4.10's, and an exhaust cutout.

Any ball park figures as to what I may be running after these??

Thanks


Also I think i am reving to high in rpms, i am shifting at about 6k. I have never dynoed so I dont really know where it drops, am I reving to high?

 

Probably the same or worse unless you get some ET's or DR's because you wont get any traction with the 4.10's on street tires.
