All of things I would have suggested have been said.It really boils down to how much it really means to you.In my case with 525 hp,468,fed with an 850 dbl pmp,I changed out rear gear from 3.54 to 3.70,and a top loader to Tremec TKO,and took what I got.My concern was cruising at 80mph and getting the rpm's down so it would be liveable,inside the car.It worked! Good Luck
