Here's one with the hood up. An unassuming black '94 GT from the outside, only the "SLEPURR" license plate gives away the 427-inch 351W with 225 AFR heads and all the 600hp EFI trimmings. The trans is a T-56, gearing is 3.73, the hit is undoubtedly muscular, and the whole thing is for sale by owner-builder Al Clark. Over $40-large is invested, he said, listing a California phone number and wearing Arizona tags. Interesting combination.
