What do you wish to accomplish by making this switch?

Easy to find an aftermarket carb to fit on your manifold, but it will be about the same size as your 4GC. Same size = No gain.

Ross Racing Engines might know of an aftermarket manifold (or an adapter) that will accept a larger one.

If you will be using the original type automatic trans, the carb to throttle valve placement will need to be transferred to the new carb.
