Just put in a 3.00 rear ratio.
Thank God you didn't buy a factory muscle car with 3.50-4.11 gears or even a typical '60s pickup truck - you might have hung yourself or something.... I have a 3:55 in my 62 wagon and it is way to low for hwy. crusing.(3,000 to 3,200 rpm at 65-70 mph). Drives me crazy.
You have 2 options:What would you suggest?
