Mike,
It is quite a challenge,but one worth while.I've seen two fe gen one mustangs not counting gas rondas cammer which could hardly be called a mustang.It had under arm leave springs and extreme set back to make it work.
Putting an fe in a 65 or 66 is basicly like building a thunderbolt from a 64 fairlane,,it can be done but not for the novice and headers look like pasta.
good luck,,T
