I think you need a different front cover to allow you to use the mechanical fuel pump.

Thanks 64 Cuda. Forgot to ask about the H20 pump. I think with the serpentine belt that the water pump runs backwards on these motors. Can the pre-magnum pumps be used since the serpentine build will not be used?
