sounds like an interesting project, Remember though, going from leaded to unleaded is a bit of a bitch depending what state you are in, obviously you will need all the emissions crap but small things like welding in a smaller fuel filler neck ( so unleaded pertrol bowser fits only ) often came up when i was contemplating a 302w EFI powered XM Falcon.
Something will have to be done to the fuel tank to accomodate the return line, mounts shouldnt be too much of a problem as the ford 6 really hasnt changed all the much since the 144 as far as block width etc goes
its definately possible but will require alot of work, im sure someone else could shed a little more light
Lets go find that Hotdog tree I planted
Lowered EF Futura
Black Steelies ( too cheap to buy proper mags )
