I have a 69 camaro 350/th350. I recently put the motor and trans back in the car. Installed a mini hi torq starter and new flywheel. Also replaced the ignition tumbler as the old one didn't feel correct and was replacing the steer wheel anyway. The original shifter and neutral safety switch r gone and I have a B&M z gate shifter which has a backup light and neutral switch on the shifter. I have all 4 tires off the ground got the engine running when I realized the spedo was moving saw the shifter in drive i let off the gas and the car stalled. The gen light was on and the key was in the run position. Soon as I moved the shifter to N the car tried to start. I turned the key all the way to off. Put the car in park turned key to run gen light on and the starter began cranking with key in just the run position. Any ideas? Car doesn't have tilt wheel was originally a 6 cyl car. Only thing I can think of was maybe I got the wires on the starter mixed up or maybe something with the ignition switch on the steer column?
