Aside from the body and suspension I'd assume. I mean the 5.0 engine, was it exactly the same engine?

mattdel

up to 85 was carbed, 86's had EFI with E6 heads, 87-95 had E7 heads, 93 and up have hypereutectic pistons.

dasfonzie

can you explain what hypereutectic pistons means?

mattdel

its creation process is different, up to 93 had forged pistons. basically the forged pistons are stronger.

intake on the 94/95 is SLIGHTLY differant, to accomidate for space

So the later 5.0s would cost more to get up in HP, as one would probably want to have forged internals?

mattdel

not really. the hypers are good for a few hundred HP. best year fox to get, speed wise, is an 89. its the lightest year with mass air, and no airbags. best motor to get is 90-92 because of the moly rings. its a toss up.

speed wise i dissagree... speed density is faster stock for stock

Hypereutectic pistons will likely last as long as your block will.

I don't like em all the same


Also, there was a small cam profile change in '89 to reduce valvetrain noise. It resulted in a 3hp loss, but wasn't reflected in the numbers Ford gave.
