The Stovebolt Site Forums The Shop Area Driveline 57 Hydramatic rearend gear recommendation

Hi,

I have a 57 Chevy 1/2 ton that has a Hydramatic. I have never ridden in a TF truck with Hydramatic, can any one comment on how it drives? Im debating on changing the rear gears to 3:38's, does anyone have this setup? Right now I have a 3:90 rear, what would the rpm's be at 65mph with the original rear. Im torn on keeping the rear end original, but also want to be able to drive it at "highway" speeds even now and then.

Thanks in advance for the input!
