1957 chevy bel air 4 door hardtop
Hey guys a few months ago I got a 3 speed overdrive trans for a good deal out of 56. I have the stock 3 speed in my 57 at the moment. My car came with 3.55’s originally but after checking someone swapped a 3.36 rearend out of a 1960 Chevy. I’m not one to go fast or beat on it, but I wanna be able to drive highway speeds no problem. I was wondering how it would be to have an overdrive on a 3.36. I do around 3k rpm at close to 70. I have a 350 with a 4 barrel, and I upgraded to an 11inch clutch. Thanks guys!
