If it rotates in the direction of a clock's hands (like your distributor) it's clockwise other wise it's counter-clockwise. Can you imagine the confusion the younger "digital clock" generation is gong to have with this one?
To ID the rotation of a vacuum advance distributor, look down onto the top of the distributor with the vacuum advance pointing twords forward. The vacuum advance will be offset, either to the left or right of center of the distributor. If the vacuum advance is on the left side from center, the distribotor turns clockwise (right), and vice versa for the other side.
Since all oil pumps turn same, clockwise, even with a reverse rotation cam/engine, the gear(s) cuts on cam and distributor allow the distributor and oil pump to rotate same as regular rotation, clockwise.
AAHHH, good info. That explains it. Wasn't sure about the oil pumps and such in the newer reverse rotation engines. I knew the pumps were the same but never gave any thought how it all worked together, older stlye pump with reverse rotation other pieces. I like learning things!
When I got my Chevelle, I mentioned to my daughter that even the clock still works. She looked at the dash and asked "Where?" I had to point out it wasn't a digital clock. We had a good laugh over that one.
