63 gear ratios
Just curious if there is a site listing ‘63 rear end ratios. I did a search here, and surprisingly only found one pertinent thread, but it was on a slightly different topic, so did not mention all the ratios.
Anyway, I just put a tach in my car. The guy who sold me the car has told me it has 3.30 rear gears. Well, I’m showing closer to 2.70. My tires 225/60/15, are 25.6” tall At 60 mph I’m at about 2200rpm At 70, about 2500 rpm I’ve verified my speedometer is accurate. With my automatic transmission that would put me around 2.70’s as far as rear end ratio. Thanks
