No. ... You absolutely cannot do this swap due to different transmissions bell housing bolt patterns. The frame stanchions for the 390 engine mounts would have to be swapped in to the '83. The 390 was discontinued in 1976 in the F250's so the 1977 had to have been swapped once before. Be sure the 1977 F250 you have is the correct year if, in fact, you actually do have a 390. Person above is an idot. Swap motor mounts, and swap engine. if you have a c6 trans in the f350 you be just fine.
