Quote: is your new motor close to the old combonation with more cubes or a whole new combo? what gear and tire are you running to go through at 9300?. are you limited by the class rules. im going to run the ram N/A gforce 10.5 class this year, i think i can be competitive. theres like 3 or 4 cars going high 850s 860s and its a all run field so if i can run 9.0s high 8s i'll be good. i have a good car i just have to refine a few things. hope that motor turns out good for you. MARK.
Completely new build,new heads,block,cam,valvetrain,The only part I kept was the crank and I am re-using the rods.
The 9300rpm was with the old old motor.I use either a 5.13 or 5.38,with a 29.5 10.5 stiff tire.I usually shift at around 8700 to 9000...conveter will flash almost 8000 off the brake.
