Got my Keisler estimate

Yeah that is the one of the problems with strokers, they don't like rpm's. Why Mopar used a 3.31 stroke for the 340 motors. Those 340's used to last 100,000 plus miles with a 3.55 gear and 26 inch tires. 3,000 plus rpm on the freeways was normal until the 55 mph limit in 1973. Even a few 440 with 3.75 stroke got 3.90-4.10 gears from the factory, many more were 3.23 thou.

I knew this old guy--back in the 1980's, he is likely dead by now. He used to tell me when the speed limit was 70 mph rush hour traffic around Detroit would go 80--90 mph. Nobody had OD trans either back then. People just brought new cars every 2--3 years, lol

You could just do a gear change, I noticed a difference going up 1.8 inches on the rear tires. Running through the gears it is a tad slower but at some speeds, like @ 40 mph in 2nd gear, I think its quicker till it hits 3rd, can go 5 mph faster before i shift.
