360 driver build

OH, there are modified bolt in kits (Trans cross member and hardware) for the A-500/518 trannys into our old cars. So skip the learn how to cut metal and weld comment.

The GV O.D. , It has the abilty to split the gears. So you would have 6 gears total.

It's a single overdrive unit, not two. You would still have a single overdriven gear above the trannys final drive.

Ratio wise, the OD @ .69 vs the OE, GV @ .78

R&P ratio X OD = A-500 OD vs Gear Vendors OD unit ratio final drive

4.56 X .69 = ........3.15 .. vs. GV O.D. ratio of .78..... = 3.55
4.30 X .69 = ....... 2.97 ....................................... = 3.35
4.10 X .69 = .......2.93 ....................................... = 3.19
3.91 X .69 = ........2.691 ..................................... = 3.05
