"FE" stands for Ford-Edsel, which was some kind of joint project. The "FE" parts are not as easy to find as others, which of course makes them a bit more expensive to build or maintain.

The 390's make alot of power. I have a 390 out of a 1967 Fairlane GT in a 1976 F100 pickup, and it is plenty of power. If memory serves me, I think it is supposed to be 335 HP stock, with 1 4bbl. It does however frequent many gas stations. I guess when ya play, ya pay.
