I don't want to race all the time. Should have mentioned that. It is a street/strip car, I only want to test improvements that I make on the strip, but it will mainly be a highway car since I don't drive it in the city if I can at all help it. I understand the lower the # of the gear ratio, the more stress they take. But it is hard to baby a car and race it at the same time, I need an all around diff that will hold under track conditions. The engine makes 500hp, but I plan on adding to that. Dana sounds like the way to go.
