I just changed out to a 383ci and also switched from a TH350 trans to a T-56. I have checked and re-checked all the wiring and everything is plugged in properly. I have power when I turn the key, yet when I turn it to start the car nothing happens. There are no sounds, absolutely nothing. So it's not that the motor won't turn over because the starter doesn't even make a sound. If anybody can help it would be greatly appreciated. I don't know if there is something with the wiring for the trans or a ground. PLEASE HELP????????
