Mine ends up being 3.21:1 in OD. It's GV unit behind a 4 speed.
(.78 reduction)
I'm about 2350 rpm @ 65 mph with a 30" tire.
2.95 would be even better, but I'm really happy with the combination.
Having driven the car for a few years now, I probably could go with a 3.78 axle, but am too lazy to change it.
I opted for the 4.11 axle because I was worried about low end torque with a Potvin 425 on the street. But it would also be fine with the 3.78
That would give me the 2.95 final.

Yep, my math was great!! Must of been doing several things at onces or a typo, who knowsActually, 4.11 x 0.63 = 2.5893, so you're doing really well on the highway!
