1952 diff ratios

[Guest]

What came stock in a 1952 customline I6 (oops!) 3spd?



What would some of you experts recommend behind such a setup for modern city/highway driving?



Is there stamping on the diff itself that will identify?



Great site by the way...

Pretty sure they came with a 3.73 to 1 standard from 49-54. Jack up the rear and turn the wheels to make sure. I run the stock 3.73 in my 1950 Coupe with a flathead-6(no overdrive) at 60 mph. An overdrive setup for yours would make the engine work less and could run at higher highway speeds.

Could you run thru the "jack up the rear and turn the wheels" part for me?

You rotate the wheel/tire and see how many times the drive shaft turns to get the gear ratio. In a 3.73 to 1, the drive shaft would turn about 3 and 3/4 times to the wheel turning once.
