Hope I am not too late for this thread, but originally, had 3.08 (1976 Chevy 2WD Pickup 350 engine TH350), changed to a 4.11 Rear Auburn Limited Slip Posi, ... how and what criteria do you use to determine what would be a good gear ratio to use for power or speed, or somewhere inbetween? Maybe even burning up the streets, chirping tires in 2nd, 3rd gear etc...???
Any thoughts? Thanks guys.
