The airshifter and all needed accesories to complete the system ,from scratch,will top $800 ,out the door.This does not include timing/triggering device(I will be using Biondo unit allowing separate rpm shift points for Torqueflite). Its not cheap by any means, but in this case I just hope you get what you pay for.That 1-2 shift is gonna come real fast in my car. I am 66yrs old and haven't driven a fast racecar since 1981! I am not gonna let my ego get in the way. Let the wind do the shifting! Bill
