5.0 efi carb convert 65

I bought a 65 Ford Custom 500 and decided, because the 240 engine was seized, to put a 302 into it. I recently bought a 5.0 EFI that was pulled from a 90's Grand Marquis and was wondering the best way to convert the 5.0 to a carb system and install it into the 65 Custom 500. Would it be more...
