If you search the forum you can find information on how to run the oil pump directly without running the engine.
This will really get the oil flowing. It's a good thing to do for rebuilt engines as well.
I made a tool from a length of rod ground down to a screwdriver-like point similar to the shape of the end of a distributor shaft.
Chuck it up in a hand drill. You have to remove the distributor, but before you do, make a witness mark on the housing where the rotor button is currently pointing.
Also, label each plug wire for correct position. Beware that the distributor can be reinstalled 180 degrees out.
The shaft of the distributor has to drop down into the notch of the oil pump. Sometimes they can be a bit finicky.
Check the oil pressure when the engine is hot. Could be the engine has worn bearings preventing oil from getting to the top.
Jerry has excellent comments here: https://www.stovebolt.com/ubbthreads/ubbthreads.php/ubb/showflat/Number/1279466/Searchpage/1/Main/186494/Words/"216+oil+pressure"/Search/true/216-oil-pressure.html#Post1279466
I suspect you have read about the 216 mains having babbitt bearings and the "art" to rebuild this part of the engine requires old time experience.
It can be done and is more expensive.
