3.31 or 3.55

your right. i didn't see it in the first post because its off the side of the screen....

Me either

Would using the 3.55 be acceptable?
I saw tonite that at 70, I was running about 2800 rpm. This is with the 3.91's.

I never noticed you have a gear vendors. If your running 2800 at 70 I'd leave it be. Your converter may slip and heat up if you go any taller on the gear.
