A Body Road Trip Car

I was running H70x14's in the back. They were retread tires that had a sticky compound. The original owner of the Cuda back in '68 put them on as they had more traction than the E70x14's that were original. That wasn't hard to have more traction that those either!. But the retreads lased about 20,000 miles of hard driving and never failed me. They were probably one of the reasons I could turn good times with the 340. [email protected] at OCIR. The tires literally filled the wheelwell and touched the inner well if I hit a bump too hard. But I could shift from 2nd to 3rd at just about 100 MPH and got the car up to 145 MPH with them (6500 rpm in 3rd). Maybe not so smart, but I was 19 at the time. This was done on the 91 freeway when it was being built and they opened a section the week before. There was a 2+ mile run with no onramps and I did this at 7:00 in the morning on a Sunday. absolutely no one around back then at that time.
@RLF Cuda Yeah, the "Exuberance of Youth". We're lucky more of us aren't dead. lol My BIL had a stock 67 273 Formula S that had tall tires on it. (Unknown long gears.) It was a dog out of the hole, and it couldn't pull the long gears up top. I told him he needed shorter tires, but what did I know? This was in the 70's, and I was a teenage punk. He was about 25, so he "knew more".

Anyhow, I should have been more precise. I'm wondering how you knew the speedometer was accurate with those tall tires. (In order to check mpg.) Of course, no internet to look up a formula. I used to run several miles on a road with mile markers to check mine.
