318 EFI and carb

I think he is wanting to know if you can take an EFI engine such as a magnum 5.2 and convert it to carbureted.

Yes you can. You need a carbureted intake that fits the heads your running. Some have dual bolt poo patterns to fit magnum heads or LA heads. You need a distributor with a vacuum advance, just reuse your old one off your original engine if is a small block. Magnum engines dont have a mechanical fuel pump eccentric. I think people run electric fuel boost pumps to the carb.
