just trying to deside wich way to go and if i went with my 350 and new holley mech pump if i can just splice in to fuel line (since in tank pump not working) or if i have to do a bunch of other mods to fuel system or do i get a block off plate and run the electric pump and get a regulator or just put tbi 305 that came with the car ( a used replacement) and run it. its a mostly street car maybe few fun runs next year at street fights here in bristol
