1966 Fairlane/Comet only.
By Dave Shoe - 10/25/2001 6:18:30 PM; IP 12.2.11.131
That exhaust manifold, also known as the 390GT exhaust manifold, came on the 1966 Fairlane/Comet.

It needed to be slightly redesigned in 1967 because one of the sides didn't quite fit the 1967 Mustang engine bay. The 1967-69 (and maybe 1970, I forget) version was used in the Fairlane/Mustang/Comet/Cougar and had one bolt relocated.

All 1966-later heads have bosses cast into them (but only drilled for small-car applications) which allow drilling the "diagonal" bolt pattern these manifolds require. The diagonal pattern was necessary to make the manifolds more "service" friendly in such a confined engine bay.
