get the 1 cyl to TDC then pull the dizzy up and reinstall it with the rotor pointed at the 1 cyl.

The next time you pull a distributor, first pull the cap off and record where the rotor is pointing so you can re-stab the distributor properly.

Problem is with the Chevy is that as the distributor is removed the spiral of the gear engagement pulls the oil pump drive such that when you reinstall the distributor if it easily engages the oil pump the gear is most likely a tooth off (about 30 degrees of rotation). Assuming you pulled it with the rotor aimed at number 1, you can either retard the setting by 30 degrees by rotating the housing if it doesn't get hung up on all the stuff around it, or you can reach in with a long screw driver to align the oil pump drive shaft so you can get the distributor in correctly. Be subtle doing this as the intermediate shaft which is the top you're seeing is aligned to the pump shaft with a plastic sleeve. These deteriorate with age and it is possible that just jamming around in there will dislodge these shafts then you have really big problems.

If you didn't align to number 1 or 6 when you pulled the distributor and now don't know where those locations are you've got to finding number 1 firing position, simply aligning the timing marks only gives a 50/50 chance of hitting it because the timing marks are good for number 1 and 6 at TDC, but just one of them would be ready to fire.

Remove the driverís side rocker cover a PIA to be sure with all the plumbing that goes over and around the thing. Pull the engine around with a socket wrench on the crank damper's bolt tuning it clockwise (it's normal direction of rotation) watching the valves sequence on number 1 when both the intake and exhaust are closed and the damper mark is approaching the timing tab then it's moving to TDC firing number 1 cylinder. Another way is to remove the spark plug on number 1 and place you finger over the plug hole, then bump the engine around with the starter. When it blows compression past your finger you know it's coming up on firing then walk it in with a wrench till the timing marks align.

Now you're going to have to estimate the distributor shaft position to fire number 1 to get a rough idea of where the oil pump drive pin is located relative to the engine. Then shinning a light down the distributor hole see where the slot of oil pump intermediate shaft is aligned and using a suitably sized screw driver gently turn it to where the distributor shaft will catch it and align it with the number 1 firing position of the rotor to cap.

Yes this whole job is a PIA.
