I just bought a beat up M880 aka a 1976 M200. The PO has replaced the original 318 with a 360 from a 1990 truck. He also installed a janky electric fuel pump as the 360 did not have a mechanical fuel pump. I can see that there is a block-off Plate bolted on where the fuel pump would go. Does anyone know if a 1990 360 would have the cam lobe for a mechanical fuel pump so I could just take off the block-off plate and install one instead of messing with the Mr. Gasket electric fuel dump he’s mounted on the fender?
