ugh, you would. just dont tell us about it.

 

i have an 82 recaro trans am w/disc brakes on the rear dual tpi on 305. im just wondering gear ratio it may

 

I take it you mean by the dual TPI the LU5 crossfire injection. So if that is the case the rear axle should be Limited Slip (RPO G80) and a 10-bolt 3:23 ratio if it is a 3sp auto. I don't even know if a manual was available for that model & options.

 

It's easy to find out.
If you don't have a posi...
Jack up one side of the car until one rear tire is off the ground. Block up a front tire and put the car in neutral.
Lay on the ground and put the valve stem on the rear tire at 12 oclock pointing straight up. Note the position of the rear U joint or even put a piece of tape on the driveshaft itself. Slowly turn the rear wheel with your hand and count how many times the tape goes around as you make two comeplete turns of the rear wheel.
If the shaft turns around 2 3/4 times you have a 2:73 rear, a little less then3 times then it's a 2:93 and a little over 3 times then it's a 3:08 and if it's 3 1/4 times you have a 3:23.
If you do have a posi...
The same process applys but you have to jack up both rear tires.
Note the position of the U joint or put a piece of tape on the driveshaft with the valve stem on the rear tire pointed straight up. Make only one full turn of the rear wheel and count how many times the driveshaft turns.
2 3/4 turns of the driveshaft is a 2:73 ect...
You probably have a 2:93 rear but 3:23 was optionalif it's stock and came with the CFI and auto trans.

I'm not sure what a dual TPI 305 is....

 

Its custom. Like the engines with the dual roots blowers on them at an angle. Same concept.
Oh wait.....maybe he meant Dual TBI.....thats not as cool![8D]
