My latest improvement to the project is a 4L80E 4 speed auto with a lock up torque converter. RPM on the highway at 70 MPH will be 2000, and 2800 at 100 MPH. This is with a 30.5" tall tire, 3.42 gear and the 0.75 overdrive gear. At the track I am using a 28" tall tire.
A toggle switch on the dash to lock up the torque converter, with a brake switch to make sure it shuts off when I hit the brakes. Paddle shifters on the steering wheel will manually control the transmission. The column shifter is still hooked up and will be used to select park, Reverse, or Drive and then once in Drive the trans will only shift when I use the paddle shifters up and down. A LCD display will show if I am in gear 1,2,3 or 4.
I had the trans built up to handle 1000 HP, and ordered a custom torque converter that has a 3000 RPM stall and the lockup. a little pricey for this setup but the MPG gain over the Th400 will be substancial.

I actually ended up changing my mind and going with a stock style tank but mounting a Walpro 400 fuel pump in the tank connected to a Rob MC 1/2 pickup setup. I am cutting a trap door at the top of the fuel tank to install some baffles, the fuel pump, and then welding it back shut.
