What will it run?

I have a friend with a pickup very simler engine combo, with 4.30 on ET streets runs 11.50's through the mufflers at 5,000alt ( drives it to the track 35 miles each way) and another that has an a body same combo runs 12.50's with a brake and no exhaust.(trailers it) Built by different builders very comparible builds, its all about the tune Engine and chassis.

flyfish.... those are good #'s in Denver
