So I just purchased an 86' GT It's in good shape, with 115,000 miles and is totaly stock other than a C4 trannsmission and 87-93 GT rear spoiler. It just needs a little bit of a tune up and of course some go fast goodies. I've done a little searching but haven't had much luck finding the info I'm looking for. I know there are some differences between the 86' and latter fox mustangs that require a little different approach to working on them, so any more info or help you guys can give would be much appreciated.
Here's what I know:
Flat top pistons with higher compression
Low performance lower intake and 58 mm throttle body
Low performance heads
Speed Density
Different shocks and struts
After I get it running well I am going to start improving the performance. First, I am changing over to a mass air setup.
I'll then be going with a completely new exhaust from headers to tail pipes. Because of the auto tranny are my choices for exhaust components limited?
Finally, I would like to do a head cam and intake swap, but because of the flat top pistons I am unsure what to go with. Will GT 40 heads work? What is a safe lift for a cam?
Also will 87-93 shocks, struts and springs work on the 86? With or without modifications.

GT40 heads will work, but i think u might need different headers to go with them, might wanna check on that. Most all 79-93 Suspension pieces are interchangable. I would prefer a cobra or GT40 intake. The auto does not limit what exhaust components u can use.

I have BBK shorty headers on my 86, but it has an 88 motor in it. Pretty much the same i do beleive. It runs real good and sounds great with bbk shorty headers and an offroad exhaust

piston to valve clearance is going to be a problem with the 86. thats why when i had the motor replaced in my 86 i went with a rotating assembly from an 87 to get away from those pistons. almost all heads even the E7TE i believe will need valve reliefs cut into the piston

no, my dad put heads off a 90 GT on his 86 Gt and had no issues. but u cant go to far with the cam with those heads due to the clearence issues.
