My 351 has the Holley system on it. I haven't found anyone yet in Georgia who can straighten out the fuel map for it, so I have a engine that runs rich for now and gets about 10 miles to the gallon. I think I would probably be sold if I found someone (or could be taught) that could work on it. I just keep changing the
oil every 400 miles or so until I straighten it out. Anyone have a fuel map for this engine?
