I guarantee you I can make 500 to the wheels through a six speed and a stock rear, probably with stock castings or TFS-AFR's on top of a 383/396 and a stock intake. Gonna take 12 to 1 compression and possibly a solid roller, maybe a large hyd would do it.

But I could do it. Would it be cheap...hell no. And you FOR SURE aint gonna strap a blower on it.

My setup would make 520-530 easy to the wheels through a six speed and a 10 bolt.
