With 30 in tall M&H slicks you knew some gears were back there, but I still drove around that way. My one GTO came stock with 3:90's with 4:33 as an option, and those were on short redline tires.

We won't talk about gas mileage though.

The 442 I mentioned got 15+ on the trip back from Colorado to S.D. when I brought it home. I also drove some 5.13 in a daily driver for a couple years. It was a 57 F350 dually with a 312 and it could pull a house. 65 was about tops on cruising speed. It got about 12 out on the road.
