I'm Turning an Offenhauser 3X1 for a 6 cyl into a 2X1 for a 4 cyl.
You are familiar with CopoRat's fuel injection conversion of a Clifford 6cyl 4bbl intake manifold. There is no reason that intake couldn't be modified like you have done to the Offy manifold, i.e. cut off one branch and block off the resulting hole. The throttle butterfly wouldn't be centered between the cylinders but many modern oem FI setups are the same way. You could have the throttle body be at the front or rear of the head depending on which one best suited your installation.
