I'm assembling my first Ford engine. 74 360. In the gasket set there is a thin o ring, about 1 1/2" dia. Can anyone tell me where it goes? The engine was disassembled by some one else so I never got the chance to see it first hand.
Yeah the distributor is the first think I thought of. This o ring is a common round one and not tapered. Unless, maybe some distributors have different types of grooves?
Ok who makes the gasket set?
Most sets are for multi year / size engines so it may not be for yours but an extra.
Also it may be listed on the box what the gaskets are and maybe a part number.
If so might be able to cross over the part number for a clue.

That's what I'm thinking too. I'm very familiar with the extra gaskets in Chevy gasket sets but with this engine It's hard for me to know the difference!
I would guess it is the lower o-ring for the distributor. My distributor on my 70 f250 with a 360 has two o-rings on it. A bigger diameter one on the top and one like youre talking about down lower.
Interesting! Mine didn't have the O ring but there is a small groove there. Not as wide as I would expect for the size of this O ring but I can see where it would seal the hole going through the valley floor. Not sure why it would be needed. Regardless, I might just install it there whether it's needed or not.
There's got to be some exploded diagrams somewhere that shows this.

Reason: A
As mentioned these gasket sets usually cover a number of years. The O ring or cork gasket may be for something like a road draft tube or early PVC system on early 60's engines.
