I got a 72 impala coupe that i aquired 85% complete. It has a 454 block w/396 heads, a turbo400 tranny. iwas told by my cousin that it needed a rear end. well since i have already been drivin a little, i think he meant a diff gear ratio. what kind of gears would compliment this setup best? I want to drive on the highway as well as smoke the tires on the street!It also has a 4bbl holley carb and a edelbrock performer intake, pics coming soon! Thanks guys.
