bobshollow,

I think the general consensus is there are NO o-rings or gaskets installed beneath the distributor.

I agree with Stuart. The 1947-54 Chevrolet Truck Shop Manuals and the 1947-54 GMC Maintenance Manual (which has a full page diagram of the distributor, with all parts labeled) do not make any mention of a distributor gasket, seal, or o-ring. There is no distributor gasket, seal, or o-ring list in a Master Parts Catalog (until 1957, for a V-8).

However, some people have posted that there was an o-ring.

You can't use an o-ring, the distributor needs to be able to rotate in the block as the vacuum advance does its thing.

I was wondering if that might be a secondary reason for the grease in the grease cup, to keep oil from seeping out of the distributor mounting hole :confused_smile: Ed

Darin; It's o.k. to use the o-ring that came with your HEI, the vacuum advance is internal on the dizzy, the body doesn't rotate. I used it too, it stopped a pesky oil leak the old dizzy had. Yet another reason to go mini-HEI??
