3.73 or 3.90?
i have a 2002 trans am auto with 275-40-17 kumho ecstca xs, long tubes, true duals. the car is my daily driver and im looking for a little quicker acceleration but dont want the 4.10s. im trying to decide between 3.90 and 3.73.
and this would just be for screwing around on the streets.
