Post your bore size and I will see if I have a spare piston.
I am not causing global warming, I am just trying to hold off a impending Ice Age!

Thanks, Dave. I have not yet ordered a new piston from Rockauto. Unfortunately, they don't have any std-sized rings for a single-piston left, just complete sets (for all eight).
I need one standard-size piston with rings for a 1966, non-HiPo 383, bore size 4.25". This motor came out of a Chrysler, and the block does not appear to have been bored over-size. If you have a spare piston with rings on it, I would happily pay the shipping.

I'm guessing there may have been an intake manifold leak at the #7 cylinder, which caused that one to run way hot.
Have you tried to wrap any logic around that statement?
My bro-in-law, a retired mechanic, is the one who suggested this. He has seen instances of intake manifold leaks causing such things. A leak at the intake runner for #7, where the manifold meets the head, would allow outside air to be pulled into the cylinder, diluting the a/f mixture, thus leaning out that cylinder, and causing it to run hot. Since none of the other pistons show any obvious signs of either abuse or overheating, this sounded like a logical and reasonable explanation for what might have caused this issue. Does this not sound possible to you? He wasn't saying this is definitely the cause. If you ask five people on this board, you may get five different explanations.
And likely not that one, or at least I would hope not............ well maybe.
