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.
LILRED66 I had the same setup but with a 3 speed, column shift transmission. I changed the 3 speed to a New Process A833 4 speed. Got a .73 overdrive and now (with 235/75R15 tires) I turn 2200 rpms at 70 and a shade over 2600 rpms at 80. 70 is easy cruising with the 292 I have as it has headers, a mild cam and 500 cfm 4 barrel carburetor. So I recommend the A833 New Process 3 speed + Overdrive transmission . | | |
