I also did not know that the FE was ever put in the N series. They kept the Lincoln Y (317 and up)for a long time in those trucks, I think there was a 302, and a 330 Lincoln Y in the N series, and as the size went up they got the Super Duty, 451, 477, 534 gas and a diesel. Did they have the FE in them?
I know some C cabs got them. We had one converted to a Hostler that had a 361 and later a 391, The gears it had, that 391w a Holley 4V and no governor would roast the tires
then a 4BT Cummins It had an Allison in all three with an adapter. Neat truck, I moved a lot of trailers around with it from perishable dock to dry grocery dock, dock to stage for the final truck hookup.
I just don't remember the N series having a 330 FE. Did they?
