just wondering if anyone could give me a guess on what it might run.
 
I'm no pro, but depending on tires and track prep, easy low 11's. That's just a guess though. Im sure the guys will chime in though. Are you really only running 15lbs of boost though?
 
Just hope the tranny is built to take that kind of abuse. I would figure that turning up the boost(maybe an alky kit) that car would really haul. Good luck on the purchase and let us know if you buy or not. Any pics?
 
And, on that combo, you should be able to run more than 15 lbs of boost. Even on pump gas(depending on the timing)

With Champion GN1 heads it probably made that power at 15 psi. :cool:

And with that second cam. in there I'm sure that helped a bunch. ;):D
