    A little more info is it street/strip or strip only? What does it weigh? Rear tire size? Transbrake or footbrake?

    No ...if it was a corvette motor he would be in the 9's already. You can run 10.50's in a dump truck if it has a corvette motor.

    That cam is nowhere near big enough for a 496, especially one with 13.7 to 1 compression.

    Is the 236/ 242 the dur @ .050? :shock:

    If so with that much compression I'd get it up in the 270- 280 range.
