Motor swap 1986 F350 6.9L to 7.3L ?

Looking for a answer to a question. I have a 86 F350 4x4 manual 4 door long bed with a 6.9L engine and motor is blown. My question is can the 6.9L be swapped out for a 7.3L engine. If so, What year 7.3L engine, and if possible what install modifications will be necessary if any?

Reason for swap- The 350 is a heavy truck and we are pulling horses, hay, wood, ect. Typically hauling 12-13k pounds on steep inlcines. Looking for more power if possible. If a swap is too much of a headache, I'll replace the 6.9L engine with another 6.9L.

Thank you.

If I remember correctly it will bolt right in. Get the 7.3 with the turbo and grab an intercooler. I had a 93 with the nonturbo and always wished I had gotten the turbo diesel or added one.
