Ok I have a 1987 F-350 and am in need of an engine. The only on that I can find in the state of New York (where i live) is out of a 1980 Ford F-350. They are both different generations but they are both 460's.

My question is:
Are they the same setup? ex: mounts and transmission

Oh and how can I trouble shoot the fule system on an 1987 F-350 with dual gas tanks?

Thank you to whoever answers.
