I think you will find the ratios in the OD too far apart for a performance car. Try finding an early trans with a 3.09 1st gear and a 1:1 4th.
Heavy wagon and looking for cruising at a comfortable rpm on the highway, so need more O/D than 1:1 as at 70 I would be turning 3300. The car is close to 4000lb and had 3.73 rear gears with 28" tall tires.
