i agree with rocco's sentiment above, shifting right before the finish line isn't gonna help you. Im curious, why are you so dedicated to shifting before the finish line?
I'm not, I want to use the 904 as a 2 speed only on the track use only first and second.
The deep first and second gear of the 904 with 2.76 rear gears would be exactly like a 2 speed powergilde with 4.25 rear gears with the same overall ratio with 1st and final gears.
So there would be only one shift at say 6000 rpm and it would cross the line in 2nd/final at 6000.
But as a bonus 3rd would act as an overdrive of sorts cause I'd be cruising with 2.76 gears instead of 4.25 like if I had a real powerglide.
I figure this is the best way just wanted some experienced input. Cause other way of saying going with 3.23 I'd have to shift into 3rd at some point. So out of the hole would be good but a dog at the end.
