I have not seen the truck yet, but the owner thinks its six volts and a pretty big motor. I told him it should be 12 volt and probably a stock 272. But if I remember correctly, some of the bigger F-series had the Lincoln Y block in a 312 or 317? If so, can anyone tell me about this motor and also if the year Ford trucks converted 6 to 12 was 1956?
