Someone mentioned that the FE can be 460ci +, and Ford do a 520ci? It isn't the FE big Block, that is the 429/460 truck engine. If you were going a big block for power, that would be the choice. The FE is not a very strong engine, generally, and has little support, by comparison, in the aftermarket.
The Windsor is a smaller lighter package, with great support in the aftermarket, and good inherant strength. I would be a lot more comfortable, building 500hp in a 351w block, than an FE. Cheaper, too.
If you want BIG power, BIG cubes, and reliability, and want to drive it normally on the road, I would always choose a 429/460 block. I don't know how they go in 67's though.....
If you want to drive it like a sports car, then definately, stay with a 302 style block, or maybe a 351w, with alloy heads/manifold/waterpump etc.
Ask Ash about the 460 engines, or Nez Demaj. They run a lot of 460's, from 532ci upto 604ci, and are running in the 7's on the racetrack, reliably, naturally aspirated, and in 1/2 chassis cars.
Summary, IMHO, without choosing aftermarket blocks:
302 stroked to 331 for high RPM, good turning and balance
302 stroked to 347 for street engine, good turning and balance
351 stroked to 393 for reasonably high RPM, all alloy accessories, for good handling Streeter
351 stroked to 408/418 for low RPM, Good handlng Streeter
If it fits (Wishlist)
429/460 for big power, street handling
429/460 Stroker for huge power, with street handling.
FE for originality.
YMMV
