if your car is a GT, it should have "GT" emblems, not "6.5" emblems. somebody with more knowledge can correct me, but I think the 6.5 was available without getting the GT package.
as far as location, somebody should be able to give you measurements from edges of fender.

The 6.5 litre emblems to th
e best of my knowledge only on the 68 "X" code cougars. But if you have a 390 in your car and are not showing it put them on. One of the ford/mustang magazines did an article on emblem placement. If I can find it I will let you know what issue.

The GT package was actually a different 390 than the 6.5 litre. The 6.5 litre had the standard 2 barrel low compression 390, while the GT's had a special cam (I think it's the same as the 428 CJ), 4 barrel carb (735 CFM?), and different heads (not sure about the differences in the heads, though).

I took the measurements for the actual holes' locations on the fender of a 68 Cougar XR-7 with the 6.5 litre badges on it. The holes themselves are 3/16 inches in diameter and there are a total of four individual holes in the fender for the badge. The centers for the holes in the top row are 5 1/2 inches and 7 1/16 inches from the edge of the fender closest to the door and 13 7/16 inches from the top of the edge of the fender. The centers for the holes in the bottom row are 5 1/8 inches and 7 9/16 inches from the edge of the fender closest to the door and 14 1/4 inches from the top of the edge of the fender.

Please check the fender of your car for yourself to see if my measurements are 100% correct. I took them with an alluminum tape measurer at 11:15 p.m. I double checked them, but you should check them out yourself to make sure that they are correct. Hell, if they aren't 100% then they're awfully damn close.

If I had your GT, I would just leave the "GT" emblems without the 6.5 badge, but that's just me.

there is a difference in the heads between a GT 390 and a regular 2v 390. I think one way to tell if yours has the GT heads is the bolt pattern of the exhaust manifold. I think the regular heads just had two bolts/studs per exhaust port, whereas the GT heads are medium rise heads and have three bolts/studs per exhaust port, with the front and back ports' top bolt holes being lower than the middle two.

wow!

all i can say is wow! this thread got mis-directed and full of misisnformation fast. all 67 390's are S code 4 barrel but not all 390 cars have the GT package. if you do not have the GT package then your car got 6.5 litre emblems. the 67 emblems are different than the 68 but the same info applies. 68's were available with a 2 barrel X code but all 67-69 390's have the same head exhaust bolt pattern and GT style manifolds (it wouldn't fit in the car otherwise). i can't tell you where the emblem mounts as my 6.5's are all S code 68's (XR7-G's, and no they don't have the GT emblems) but i can tell you your car is not a GT if it came with those emblems. hawkrod

What Tom (hawkrod) says is correct, I would add that the only way to prove an "S" code Cougar is a GT for sure is by purchasing the report from Kevin Marti.

The X code 390s did not have lower compression just a different cam, intake and carb. 2 inch dual exhaust were used as well.

It doesnt take a lot of work to make an X code 390 perform well...

The X code cars are a blast to drive stock. Mountains of tire melting low end torque. That low, beefey, burbling exhaust! Got to go outside and start up one of my cars now that I got excited over this.........

I have some research to do then, if the heads of x and s code 390's are the same. I have hooker headers installed on my 390, the top bolts on the front and rear exhuast ports on both sides are lower than the middle two, and lower than on the header. I figured that the PO puchased the wrong headers from hooker, since I was under the impression (wrongly I am finding out!) that the S code had medium rise heads as opposed to low rise heads on X codes, therefore possibly making the exhaust manifold bolt patterns different.
maybe I have heads from a different FE engine?...or hooker messed up, back in the early 80's when my headers were manufactured?
I am interested in this, I would like to know exactly what I have!
for those interested you can see a pic of my engine in the owner's gallery.

GT heads

all 66-69 GT heads have the outer two top bolt holes lower than the middle two. if your header flange has all 4 holes at the same height then they are for CJ heads. most headers have sloted outer holes to fit both even though exhaust ports are not the same and some nasty mismatch can occur. hawkrod

Hey boilermaker there is one difference between 1968 "X" code 390 and "S" code 390GT heads. The 390GT had smog holes drilled in the heads, the "X" codes did not. Thermactor smog pump and associated plumbing was a 50 state requirement in 1968 for the 390 GT engines. The "X" code engines did not receive smog pumps because the 2V Autolite carb ran clean enough without it.

Also, the 390GT heads had slightly stiffer valve springs. They were still pure crap from a performance standpoint, if you still have the original springs I recommend you throw them in the trash.
