Reply to "Ford Manifold ID - Help Requested"

Hello René

That is the 1972 Cobra Jet manifold, designed for a spread bore 4300D carburetor. Unlike the 1973/1974 manifold, it has no channel alongside the carburetor mounting flange for EGR. If a person feels they must use the 4300D carburetor, yours would be the preferred manifold due to the lack of that EGR channel.

However, the earlier D0AE manifold (designed for an Autolite 4300A carburetor) and a 650 cfm or 750 cfm square bore carburetor (aftermarket) would be a better choice. Even a 1970 Autolite 4300A carburetor is calibrated better than any of the 1972 - 1974 Motorcraft 4300D carburetors ... and the appearance is virtually identical.

If a person feels they must have an iron manifold and Ford carburetor to pass inspection, a 1970 induction (the D0AE manifold and the 1970 4300A carburetor) gets my vote. I would be surprised if any inspector in Europe was knowledgeable enough to discern the difference between a 1970 induction and a 1972 - 1974 induction. The inspectors at the California smog stations back in the 1970s were not.
