I do not know the differences in oil pressure/oiling from the 216/235 prior to 1954 and after 1954, but after 1954, running the drill in the distributor shaft gives you maximum oil pressure and max oil to the rockers all at the same time. That movie is here:
2:43 into it. It is even a rechargeable drill. Someday I plan on getting back to the 216 project and I will know. Others, like Dave (above) know this stuff by heart. You have come to the right place.
