I have recently purchased a rust free 1987 Chevy R30 single cab, long bed, dually. I plan on swapping the blown up TBI small block for a gen 6 454. It will be going from TBI to a carburetor. Now my question revolves around the fuel system. Since 454 doesn't have a provision for a mechanical fuel pump how I plumb the fuel system to be able use both left and right side tank?
