I have a '66 C-10 with a factory 3.73 and a 420 Muncie 4-speed (granny low) and a factory 327 cid. I would like to change out the ring and pinion setup for enhanced highway performance. What am I looking at for a new setup that will give me 2,200-2,400 rpm at a speed of 65-70 mph?

Your input is appreciated.
