Hey guys im 21 and I just got a 98 GT the guy I bought it from said that it has the 99 motor in it. My question is how do I tell the difference since the vin is for the 98 motor remembering this is my first car and im just now trying to pick up the lingo?
The 98 has 2 coils and plug wires (while the 99+ went to COPs (individual coil on plugs, no plug wires). Here's a 98 motor:
Oh WTF - this place is so juvenile - NOW you can post links to even Brad *******'s website?
TO BRUISERDOG03 - substitute 'brad *******' without the space into the link to see a 98 motor. You also might consider joining:

Stangnet is getting ridiculous.
OK, let's try it this way, since Stangnet won't even let me post his last name. B R A D B A R N E T T . N E T
Yea I have a 98 motor just trying to figure it all out I misunderstood what he was saying I have PI heads and cams. Whatever that means? Where could i find information so that I can start working on my car? Im just so new to this and id like to start doing some work myself and gain some knowledge. Thanx for the patience.
Ahh, ok, that makes more sense - the PI head swap is common with the early 95-98 4.6L. The PI stands for Performance Improved and it was a GREAT improvement. That's why you see the 95-98 motors rated at 225HP while the 99-04 ran at 260HP. That was essentially the only difference between these years. In addition, by adding the PI heads to the early 4.6L, the compression is actually increased a little (sorry, I don't have the exact #), so your bottom line, at least what I can recall, is likely in the neighborhood on 270HP, or around 220 to the wheels. I'm giving you just what I remember seeing, so those who have done the PI swap might chime in (and correct me), otherwise you can start a new thread to pose questions for exactly what you need.
Best of Luck!
