What's the intended use? That makes all the differance. Drag racing puts a lot of strain on the trans; you'll ruin a T56 in no time. Road racing should use a TKO with a .82 fifth. Street cars can use just about anything.

First, decide on exactly what your use is. Then take a look at the chart and see what gear ratios will fit you best. Look for the strongest transmission in that catagory. You can't get too strong of a trans.

If nothing off the shelf meets your needs, call Gordon and have him build you one.
