Job...
I've got a "draft" of exactly what you are looking for. It's part 1 of a three part article that will be published in an upcoming issue of the IHSTO club newsletter. The step-by-step is complete and validated many times over, including just last week on two different engines. The "background" information is still not finalized.
If you would like a copy of the very rough draft (no jpegs imbedded), send me an email to:
rodelizrd@gmail.com
And I'll fire it back atcha. It's very detailed regarding "what" and "how". I won't post that article here as it's intended for the club newsletter, but once the newsletter is mailed out, it will be available online at:

The overiding reason to do this is to prevent damaging the cam bearings when rotating an engine that has been sitting for an extended period of time. This is a peculiar anomaly that affects the ihc-produced I-4 and sv engines.
The "tool" I use for doing this I made from a 3/8" "aircraft drill" bit (12" long), ground to the same pattern as the drive tang used inna ihc-version distributor. The tool should be a fairly hard material, a long, hd screwdriver shank could be reworked also.
The tool should be ground to fit the oil pump drive slot nicely, not just something stuck in the hole! Otherwise, you can damage the oil pump drive connection.
Here's a shot of the tool I use, it should be turned with a hd drill motor capable of sustained operation at a minimum of 1500rpm.
Need more help? Just ask!
