Old Race 340 Teardown
OK, yes, that's exactly the kind of feedback I need thanks so much everyone. I also went hunting into my old books and came up with this chart that shows several types of seals and o-rings in the distributor base. Since I'm depending on the added "shim" height of the steel seal that I have I think I will re-use it. I'm not sure about using spray copper seal, or other sealants, on it since it still has to slide when I adjust the timing. I guess just fingers crossed that there won't be too much oil seepage here. It looks like that Fel-Pro gasket is pretty common so I can use that as a fall back. But if anybody knows anything about that steel version that I have I'm all ears.
Perhaps I should start a new thread for this engine build-up? - Jim
