391 to 460
They are different engine families and a lot of changes will have to be done.
The 391 is a FT and is the same family as the FE which is 352,360,390,427, and 428. The FT is a 4 bolt main, and a heavy duty engine. One of the above engines would bolt in, even though it wouldn't be as good of an engine for the comercial app.

In the still cool hours of the night, you can hear chevys rusting away.
