I pulled it out to check the seals on the shaft, but it was dry as a bone. The very slow leak is at the lowest "weep" hole at the bottom of distributor's body. I did over-fill the crank case on the engine's initial in-car start up. I'm thinking the oil was forced up the inside of the distributor shaft.... While the engine was still on the dyno, no leaks were noticed.
Any clues?

Guys, the oil is seeping from the body of the distributor above, not the shaft penetration into the case. The shaft seals are fine and the shaft and the case port are dry. Seemed pretty screwy to me and the builder, as a matter of fact. This is why I asked if anybody ever heard of such a thing.
On the other hand, I realize that I'm pretty spoiled by the fact that my last motor never leaked a drop in the 6k miles I had on it.
Yes, the SVDA works great especially if you are using a 30 or 34PICT. It eliminates the horrible flat spot that you get with the 009. When using dual carbs, it isn't so much of an issue though. Dual carbs will benefit from the SVDA as well but they do not have the flat spot like the single carb has.
