I know that I'll probally get some flack for this but downgrading the transimssion to a 350 turbo will save gas by weight reduction; also, it takes less energy to rotate the internal mechanisms of a 350 compared to a 400. You will get identical performance from a turbo 350, the difference is that it isn't as durable as the 400. (The tranny rebuilder who built my previous 350 and a professional drag racer/drag racing car builder bot agreed that for engines >500 hp, a turbo 400 is a waste of engine power. They were running turbo 400, but their cars exceeded 500 hp, and a 350 wouldn't live that long married to such engines.)

Smitty is running a lock up tranny. I only drove his car through a residential neighborhood, and a short run on a 35 mph highway, so it wasn't like a real test run. Even so, it was enough to get a small taste of 1-3 shifts. It seems like a nice set-up, and his transmission would be my selection as an upgrade.

As Bob is running, my car has a 3:23 screw. That's about as loose of a screw as you want if you want to consider the car something you can drive other than to the gas station and the strip.
