Your not going to like the mway it works at5 low RPMs. As I said eariler I wouldn't use anything less than a 2.94. I'm running a 410 stroker with a 2500 stall and it doesn't like the 2.94s I'm running now. You'll not get full converter lock up in town driving. Which means higher temps and less milage.
I'm running a 410 also, with a looser 10" converter and its awesome, especially with 26.7" tire. Maybe my cam/intake setup is milder, but I have had this combo for years and love it.

Thanks for all the replies. Lots of good information. I especially found the visual Speed/RPM calculator helpful at http://vexer.com/68rt/speed.html
With my 25.7" rear tires, 2.94s would give me 2730rpm at 70mph and 2.76s would give me 2563rpm at 70mph, not accounting for T coverter slippage. My dual plane 360 has good hp & torque between 2-5000rmp.
Since I don't have the funds for a OD trans swap, I think I'll go with the 2.76s. Since my stall is 2200-2400rmp, I'll still have some take off power, I just won't be posting 1/4 mile records. Plus, I found a NOS 2.76 R&P on e-bay for $75. Anybody see any problems with this set up?
Randy,
Good pick on the 2.76 gear, you will like them.
I run a 32" tire with a 3.08 gear, and 94 mph at
3000 rpm is just plain fun! Bottom end?? Enough
to boil the tires if needed and still take my
buddy's mustang gt off the start and top end.
Also, if needed, you can always toss on a 125
shot of juice. That's in my next plans.
Snap your neck, mega G-force launch, is all I want!

G machine has one of my favorite cars on the site. He still runs real good 1/4 times and has a good streetable gear. I don't consider 3.23 or lower good street gears, most cars can't hook up that much tq on the street any how. I would say get the 2.94 or 2.76, I am running 2.76 behind my mild 318 and it is a blast, I do have a low geared 904 to help it off the line.
I am not causing global warming, I am just trying to hold off a impending Ice Age!
