7 and 1/4" gear ratio?
I have a 1972 Scamp with a decently built 318 and I was wondering if anybody knows what gears came in the 7 and 1/4" rear end. i ran the numbers a long time ago and all i found out is that it is a 7 not an 8 and 1/4. im gettin the car dynod on wednesday.

Geez, just jack up the car!!
I doubt this has a posi, so you'll only need one tire up. Jack one rear up, and support it safely. Get a buddy, or get yourself where you can watch the driveshaft accurately.
Mark the tire, or use the valve stem. If you don't have posi, you can now turn the shaft when in neutral. Turn the shaft once, and the tire will turn "double" the ratio. That is, a 3.23 will turn the tire 6.46 times
If you really want to get "accurate", mark the shaft so you don't get "lost" and turn the shaft TEN turns. Of course now for 3.23, you'll have to turn the tire 64.6 times!!
