I came across a barn find Ford 390 with horizontal exhaust manifold bolts and some of the wierdest shape manifold i have ever seen any ideas on this one? It has a Factory Four Barrel Intake Manifold and where you add oil is in the intake manifold right beside the valve cover on the lefthand side. It also has Powered By Ford Chrome Valve Covers which i rarely have seen before.

FFR428

Take a look here Ford casting ID numbers and part identification info for Mustang Shelby parts see if anything matches. Also see what the casting numbers are on the various parts. The PBF valve covers are 67 up. Intake sounds early and should have a casting number. Exhaust manifolds could be pickup truck. See what you can find out and post some casting numbers if possible.

Hi, I could be wrong, but it sounds like a 428 to me.

I did get the casting numbers off intake manifold and block along with the firing order.
I would have gotten the casting number off the heads but i didnt want to mess with it since it is so dirty.
