Aren't most of the modern retrofit throttle body EFI systems now running basically 8 MPI injectors bunched together and running high pressure (50PSI or so) and squirting it in the throttle body?

Another benefit for modern cars is that a dry manifold can be made more effective at ram tuning and physically fitting into any given engine compartment than one designed to carry a mix of air with fuel suspended evenly into it. The beer barrel intake on a magnum or modern hemi is a perfect example, they have even length and shape from one runner to the next as well as a long length that would let fuel drop out at low velocipy. They would both have terrible distribution with a carb (either a down draft on a magnum or side draft on hemi).
