I just went through this on an 85 SS 440. The manual says to remove the bleeder screw on the pump and pull over the motor without starting a few times until oil comes out of the hole. Replace the screw. Then start the engine and run at 2000 rpm for two minutes with the oil pump cable pulled to the wide open position at the carb. Even though yours is a differn't modle I would think it would be similar. On mine it is nearly impossible to reach the screw once the engine is installed. So I skipped this step (the pump was full of oil when I put it back on) and it seems to be working fine. Hope this helps.
