my teacher in auto tech at school has a prototype explorer 5.0 motor sittin on a stand in our shop in a corner on the intake it says prototype.. id like to buy it but.. im not excatly sure if this motorhave p heads gt 40p motormaybe maybe not but if it happens to be p then my question is how much of a difference hourse power and torquewise would it make my 5.0 in my mustang if i used the heads and intake off of the explorer motor for mine while i use the explorer motor as a building project later on? any difference at all?

 

usually 30-40 with cam

 

what kind of cam would work with the setup to make the 30 40 horse power difference
