Re: gear ratio

The most common ratio in the '60-'62's that I've found is 3.90's

Re: gear ratio

I think two choices were 3.38's and 3.90's. The latter being the more common. I've seen 3.38's on a factory automatic '62 with a 283 and a glide.

Re: gear ratio

To check rear end ratio jack up one tire if you have an open diff, or both tires if you have a working posi or locking differential. Rotate the tire one full revolution for posis and lockers and 2 full revolutions for open diffs. Carefully count the number of full revolutions the driveshaft makes. This is your gear ratio. In other words, if the drive shaft turns 3 ¾ turns, you probably have a 3.73 gear ratio. Turning the tire for twice the number of full revolutions and dividing the drive shaft revolutions by two will give you a more accurate reading.

Re: gear ratio

Have you checked the back of your seat for the build sheet? That's how I found out what my 65 had.
