I drove a friends Sport Coupe in Florida with the 3:1 first gear and a 37% OD. The car had the smaller diameter 16" tires and a hopped up engine. It ran great on the road. I ordered the same ratio trans for my Sport Coupe again with a reworked engine and 16" wheels. Probably put it in when the driving season stops. I got mine from Sheridan transmissions (616-837-6477). It uses the stock bellhousing, and a shortened drive shaft. He cuts the top bolt off of the universal bell and it just clears the cross member. Just shims the brake cross shaft down about 1/4". I will post some pictures when I finally make the switch. Using the 16" tires with a 3.78 rear is almost the same as the stock tires with a 4.11 rear.
