I am replacing the stock intake manifold on S/N 4503 with a aluminium Blue Thunder Intake Manifold, I purchased from Hall Pantera. This model of the Blue Thunder manifold, has special machining on the carburetor mounting base, to level out the carburetor in a Pantera...
What I really like about this manifold, so far. Is how much it looks like the stock OE manifold. As you can see in the attached photos, i painted it high heat Ford blue to hide the fact, thats its aluminium and not cast iron...
