Just found this board today. I have a '77 ford motorhome with a 460. Motor is supposed to be freshly rebuilt. Bought it in '06 been sitting in rv park since '07. During the short it was running it ran well for first 300 miles then started dying at highway speed then would catch & run fine for maybe 50 miles & do it again. Gotten progressively worse. Has 2 tanks, see-through fuel filter ahead of externally mounted (inside frame rail) electric fuel pump. Coil is new, thought fuel had trash but was clean. Ford dealer couldn't figure this out and I too am at a loss. Also, I think block is newer than '77 as mechanical fuel pump boss is not machined. Any ideas? I need to get this thing running as I'm about to be thrown out of this park for rv being too old. Also on un-employment so don't have much money. If ya'll can, please help. Thanks.
