A good buddy of mine bought the Trick Flow setup for his fox. Stock bottem end with just the trickflow set up and he put 310 to the rear wheels. He runs 8.0's in the 1/8th babying it. He comes out of the hole pretty soft and it runs good. It's in a coupe so if weighs less but it would give you and idea of what kind of power you would make.
i got ported and polished holley heads, stage 2 cam, and a trick flow street burner intake and my only other mod right now is exhaust. with a good launch and perfect shifts i run a 12.7 but id say im 12.9-13.0 consistantly.
