popping noise 450 slc 1980

when i start it starts a little rough and when i start out it accelerates slow and the carburator makes popping noises and it is slow to get up to speed. when it get to speed it goes ok but when i hit a small grade and go uphill it seems to lose power and on the down side of the hill it picks up speed. the plugs. wires cap and rotor are all new. also new fuel filter. can anyone help me on this. i will greatly appreciate it. someone told me it might be the fuel distro or something like that. thanks again/ dominick.
