I know this is a Mustang site, but I have a stock 351W with less than 4K on it in my 92 F 250 Flatbed. I'm getting ready to do the same thing that "mcc351" did with his installation of an Edelbrock Pro Flo 4 EFI System 35950 installation on Stock 351W. He is the only one I have found online who has done so, so far so I need to pick his brain a little regarding his installation.
