The 72 Demon Follies....

Thx Don. You're right on the gear. I've taken it out the back door a couple of times at 11.31@115+ but the rpm was between 6700-6800 and it really was not pulling hard. I figure the 4.10 will do a couple things - probably drop the flash stall from 5000 down to something lower (directionally correct if I get a sketchy track) as well as reduce the rpm down to a bit over 6000 at the stripe. "We shall see" as "your results may vary" as they say. If I'm wrong, well, maybe try a 4.30. Or just go race and have fun whatever it runs!!

usually about 250-300 rpm difference between those different gears.
I doubt you will see much if any difference between any of these gears on a time slip. You are right, live to fight another day, no since wringing stuff out every pass.
I shift mine at 6300
