"You could not get a 460 engine with 4WD or w/a manual transmission until 1983."

I came back and re-read this thread. The statement Bill was trying to make was that any Ford truck with a 460 had an automatic transmission until 1983, then the 460 had a manual transmission as an option. The 4x4 didn't have a 460 until 1983, as an engine option.

Since both these hold true, that means no F350 4x4 prior to 1983 had a 460. No 2wd F350 w/460 had a manual transmission prior to 1983.
