Glad you finally made it to the conversation....we got another Nova here. wink

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.

My S54 equipped I4 MR2 has the following
Gear Ratios:
5th: 0.820
4th: 1.028
3rd: 1.322
2nd: 1.960
1st: 3.285
Final Drive Ratio: 4.176
Yielding a Crawl Ratio = 1st x Final of 13.718

To panic's point the 10x CR is a floor. My NA '92 MR2 left the factory with a 135hp . . . and the Toyota engineers chose a CR approaching 14 . . . in a stick shift.

My favorite gear to date is the 4.56 gear with a 27" tire and an overdrive. Car feels like a rocketship (though technically still slow) and did well with the overdrive. Even drove to Salt Lake City at 80mph on I-80 at 3200rpm for a hundred miles each way.

Currently have 3.42's and they are pretty decent, but have another set of 4.56's ready to go back in.

My car has a 200-4r in it for an overdrive.

Interestingly enough, a bunch of my friends that run single digits in the 1/4 have been switching to a powerglide with gear vendors on the back and gearing appropriately for the gear vendors to shift going down the track.
