Most any of the full sized Ford, Mercury, or Lincoln from the 60's, the majority of them came with an FE engine. Ford pickups had an FE engine available from the 60's til about '76.... A mid sixties shortbox halfton would make a very nice home for it!!!!

Can't tell you much on the FMX's, I usually go with a 4 speed behind an FE. The extra gear sure does make it easy to keep the engine in it's peak torque range....

As for the t-bird, either a Big Bock or a Windsor would be an easy install. All the parts are available aftermarket.... Headers, oil pan, etc.
