Old Race 340 Teardown

Ok, now I get it.

I’ve seen distributors with the tang too long.

If you need some clearance there just grind a little off the bottom of the tang.

I would not use a gasket to shim the distributor up.

He's gotta have "something" to seal the distributor. He said the distributor does not have a machined slot for the O-ring seal.

To the OP, here's what "I" would do. Spray both sides of that existing seal with a good coat of Copper Coat spray and let it tack up. It never dries completely, so it will stand the distributor being turned to adjust timing and still seal fine.

Right, I knew that. That’s why I said not to stack them.

What am I missing? Doesn’t this block take the same gasket as regular small block?

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

I have that book. It's a good one.

I would leave this thread going, so much awsomeness and history in one location, plus it will be easy to revert back and see where it all started. Just my 2 cents worth
