Hi,
I just bought a 94 F350, 4X4 5.8 automatic. The engine is shot, they tell me it froze last winter. I have access to a 93 F250 with a 5.8. Will I have to change any wiring or sensors or is it a direct swap. Also, these 5.8s are they M's or Windsor's or is it still mix and match.

 

Should be a direct swap. Both the engines are Windsors (351M's were phased out in the early 80's).
