1957 Chevy Hydramatic rear end gear change
Hi,
I posted this on another site, but wanted to know if anyone has lots of experience/knowledge with the Hydramatic trans. Just a background, I have an 1957 Chevy 1/2 ton truck that originally came with a v8 and 4 speed trans. I picked up full running gear from a hydramatic truck and was going to swap those parts to my truck (front and rear suspension, rearend etc (mine was changed to something else from a PO). I have a ton of Hydramatic questions so if anyone wants to share their knowledge im all ears! 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! |
