4.6L 3v information wanted!

[bmxmon]

Hey guys im trying to gather some information about the 4.6L 3V motors. Im contemplating on swapping one into my 65 Mustang at some point. (Though still very undecided) First and foremost I would like to know from those whom have drove them what they think of the motor? What is the aftermarket like as far as computer choices/turners go? Is the computer a stand-alone ECU or is it completely wrapped up with other systems of the car? How much would you expect a 3V and 5spd combo to go for out of a wreck? Any other info tips would be great, thanks guys.
