Hello everyone. I have been lurking around for a month or so while I was rebuilding my 68 GT engine. I need a little information about the carburetor spacer plate. Can someone tell me the thickest plate I could use? From what I understand, ford used an 0.28 " thick spacer on the 390 GT engine, and I am guessing it was so thin to allow clearance between the breather top and the hood.
Any help would be appreciated.

Why would you need a thicker plate, on less you are going do some high RPM driving, a thicker plate would not do you any good.
You could lay some modeling clay an the air cleaner lid, close the hood and check for clearance.
By the way, welcome to the forum, I should have started with this!
Thanks for the reply, and the welcome. The reason I ask the question is that I am having a hard time locating an original type spacer with the vacuum port in the rear.
Not sure that there should be a vacuum port on the rear. FE engines used a PCV transfer tube between the intake runners, which connected to the PCV valve.
We sell a reproduction bake-o-lite spacer plate for the 1968 390GT.

Wayne,
Was this a 2V or 4V engine? I have a 2V type with the port on the back and it is about an inch thick. It’s possible that there was a 4V version of this.
