If 3.08 is the kiss of death, then the TH 350- 2.73 gears that I have are the Zombie Appolicapse!!! According to The "Gonlicuator" switching to a 2.74 first gear TH 200 won't help much at the drag strip. Jay
Glad you finally made it to the conversation....we got another Nova here.
Yeah, I keep quoting the "kiss of death" 3.08, but he was just in reference to early Chevy IIs with a Powerglide in comparison to the 3.55 it had initially. I don't think that applies to the TH350 because of the deeper first gear. The question at hand is that TonyPA has a 3.08 Posi on his Nova and is wondering what he should upgrade it to.
For me, my 2.73 is the performance ratio for 3.50 1st Sag, while the 3.08 would be the high perf upgrade.
