if it "made a noise" over a lifter knock (mild knock clearly in top end of motor) then the damage has been done. you aren't gonna hurt it worse by starting it. you can check the oil pump by hooking up a pressure gauge (or turning on the ignition so your factory gauge can work), pulling the distributor and, using a oil pump turning tool, spin the pump with an electric drill...if the gauge comes up, you're fine.

although, i wouldn't go through all that trouble. that engine is most likely just fine. just start it!
