Tony's car is powered by a 350 Chevy with a 2 speed Powerglide transmission.
The rear differential is a stock NON-Turbo II 4.10. Believe it or not, the rear tires are 26x10 Mickey Thompson slicks on 7" wide front wheel drive wheels (offset unknown).

At first glance, the hood scoop appears to be a stock Turbo II.
It is actually a stock scoop from a '84-'85 Capri, bolted to the RX-7's hood. This scoop clears a Victor Jr with a 1-1/8" spacer, and a 3" air cleaner.

We don't have any timeslips from this car, but I think we can safely assume that it's fast. Tony estimates mid 11s.

This car also has the Capri hood scoop.

Would you believe TWO V-8 powered RX-7s in the same neighborhood?

These timeslips say it all. Tony is car #5042.
