swapping your parts over to the explorer motor will net you a slower running car. those engines had lower compression than the mustang motor.
you want to rebuild your current motor and get some P heads, and a better cam

Nope like adder said they have dished pistons with valve reliefs and the regular mustang had flat tops with valve reliefs. The exploder motor was rated at 215hp with gt40 heads and intake while the stock mustang was rated at 225hp with e7 heads and crappy intake. The Cobra motor was only rated at 235hp with gt40 heads and cobra intake and different cam.

are the pistons the same? everytime i hear about people getting gt40(p) heads they said they milled off .030 to square the deck and get the compression back to normal. so i assume gt40's have larger cc chambers?
