My Canadian reference book says both 3.36 and 3.08 for automatic cars, but does not distinguish between 6 and V8.

 Is that out of a '64 Roger? What's an easy way of telling what gears are in my posi?

 Is it in the car or on the bench?

 Hi Carl ... in the car.

I take it, there isn't a easy way when it's under the car.

Jack it up, both wheels off the ground.

Rotate the wheels so one of them has the valve stem at a known spot (let's say the bottom)

Put a mark on the driveshaft at a known spot.

Roate the tire exactly one revolution and count the number of revolutions on the shaft.

A 3.08 ratio will rotate the driveshaft 3.08 turns for every one turn of the tire and so on...

This only works IF you have a posi.
