Pieces of steel in cylinder??

Perhaps. Super nice guy, had a VERY nice GTX in the garage, and I’m maybe a bit more trusting than is good for me. He’s actually the one who told me about this forum. He probably also sniffed out my ignorance from a mile away. I might be one of the smartest guys in the room when it comes to woodworking tools, but I’ll admit I have a TON to learn about classic cars.

He included paperwork from the rebuild, I’ll need to dig it up. But yeah, the more I work on it, the more doubtful I am of WHEN the rebuild was.

And I’m very appreciative of the help so far. You guys are great.
I would take the paperwork back and ask him what engine it goes with - certainly not yours. Make him sweat for what he did. Let him know even though you are not an experienced engine guy, you know what he did. It is obvious the paperwork isnt for THIS engine.
