Found a web site calculator for figuring engine RPM related to speed... with a 2.76:1 rear end and the A904 transmission, the engine would be running about 2300RPM in 3rd gear at 70mph... that's not bad at all, I think.
So... that whole 'overdrive transmission' plan is even more unlikely to happen. If I ever get around to beefing up the engine, a 727 and new driveshaft is likely just to handle the horsepower and torque, but can probably leave the rear end ratio alone, though of course it needs a limited slip differential... ;-) (that's like phase 4, though... actually I don't know what phase it is, probably phase 3, since my previous phase 1 and 2 are not just one big phase to get it running and safe on the streets.
