When we put the 350 motor in my 52 it was from a 1979 standard tranny pickup. Couldnt get the thing to turn over to try to start. I used the wiring harness from it also. Took me till the next morning to think about jumpering the little connection that makes up when you push in the clutch!!! DUH I thought about hiding a switch in line with the thing just for the reason you guys are talking about. What do you think??
