Yes its possible but it takes to much time and money, you'd be better off just swaping the whole motor.

Not a lot of time but it would be an *** load of cash unless you have a 4v sitting around with bad internals. Also remember you CR will decrease with 4v heads because of the design of the head. YOur CR will fall to around 8:1 "DEPENDING" on what year you have and year and Model 4v came from.

3v block has different coolant passages so they wont fit.

There's usually one or two at the online junked car places. Sadly, there are enough people wrecking machs and cobras that there is an engine market there. :'-(
