Though I did not measure from deck to ring, I would estimate 7/16” down when I measured the ‘top’. I will get a few more measurements toward top of #1.

Am I wrong In Thinking that my ring gap should be .017 max, and have .063 at best… .129 worst … so might be a junk block? .112 is more than .060 over (which I assume is the max overBore). Or since I don’t know original ring gap… that ring might be the problem in my math…. ?
Edit: ^nevermind .129/3.14 is .040 over so I think I jumped the gun there.

I will probably do the other 5 pistons measurements tomorrow assuming I have some time after work.

I was not planning on needing all new bearings and pistons, but what’s another 7/800 dollars for an old truck…

I am guessing 1200 in parts and 1500 at machine shop. That’s likely a low Guess.
Now to find a machine shop.
