There are four ways to find a ratio.
1 A dealer can normally tell from the vin number.
2 There are normally tags or labels on the axle that have part number, gear ratio, and fluid requirement
info.
3 You can count how many times you have to turn the driveshaft to get one complete turn of the tires.
4 You can divide the number of teeth on the ring gear and divide by number of teeth on the pinion.
most common ratio is 373
3.08 makes a good ratio for economy. 3.55 for more power when towing.
If you're talking about rear end gear ratio, it means there's one complete turn of the axle shafts for every 3.5 turns of the driveshaft.
There will be a small metal tag on the rear diff. It will tell you your gear ratio, and will have an "LS" after that number if you have a limited slip.
That all depends on the gear ratio in the rear end. A 350 would be better.
If it has stock-type tires, a 3.08 should work good for economy, and a 3.50 for power.
Rear end gear ratio and tire diameter are required to make the calculation.
3.90
Yes I have one in a1990 silverado short bed with 350 and 5 speed automatic transmition.

Probably either 4.33 or 4.56.
