My 1978 Chevy Malibu just came out of the body shop from a great restoration on the body...the body is finally GORGEOUS! ! ! With that said, I'm running a 355 small block, turbo 350 3 spd tranny, with 411's in the rear end. My problem is im doing 3500 - 4000 rpm on the highway at approx 60 mph. I know this can't be good for the engine and tranny. I'm looking to update either the tranny or the rear end to todays technology and highway rpms. Any Suggestions?
Depending on how you want to drive your car. You can put a O.D. Transmission in it, or change the rear-end gearing in it. I have a set of 2:73.1 gears I took out of my 1978 Malibu wagon. I put 3:73.1 in it. These are just gears. My wagon is a Factory 4SPD.
