RE: 390GT using 428 CJ Exhaust Manifolds

The engine you pulled out belongs to a '67 GT. The block was cast in April of '67. Way too early for your car. The heads will have casting dates under the valve covers centered near the valve cover rail. The intake should have a date code, too. 68 heads would be C8AE-H's.The manifolds are definitely CJ's, and are the best flowing FE's that will fit your car aside from R-codes perhaps. A decent machine shop can "move" the holes in your GT heads for a proper fit. They will support flow for a 12-second 428. The "matching numbers" thing, I fear, is going to be a dissapointment.
This thread, so far...
