I will be eventually installing my 340/727. A while back I bought a 340 six pack and parts from the radiator to the drive shaft with t/a exhaust that was supposedly in a 70 challenger. These parts were shipped to me apart on two pallets, so the engine and trans were not bolted up. I think the 340 is a '72. What I would like to find out if there is a way to determine if a transmission shift kit has been installed. I have a need to chirp gears.
