Why not just change out the rear gear ?
My roadster has a 350/350 9" with a 2:79 gear and it'll run all day long @ 75 -85 and not twist it over 2500 with a 31" tall tire
Rear gear change is a lot less expensive than a tranny

I still don't think I want a stick in this car so I keep looking at Gear Vendors OD's and other automatics with OD.
