1124 final report.
I'm not sure if I ever confessed what was wrong with this hunk. The new yellow bearings when they came back out showed signs of contact on the top, bottom, top, bottom, top. The case is obviously tweaked and was welded where something happened near the points end. A leak down test showed two cylinders leaking badly where the sleeves were too low in the deck to seal against the copper head gasket.
The main journals on the stroker crank run pretty true with a dial indicator when I can turn it with two bearings in a case and it doesn't climb up.
The tight spot was caused by a scored piston and cylinder down low where it wasn't exposed during rotation. I'm pretty sure it had a folded oil ring. The piston was missing that ring when it came apart so that explains why the PO abandoned a 72mm stroker motor.
I've pretty much written off the cylinder, sleeves and engine case. I doubt that I'd use the crank and for sure not the aluminum rods. The head and rocker towers still look good though, that can still go on the new motor however it ends up.
So much for "just getting it running" Thanks for the advice and sorry I didn't just tear it down to begin with. It was a learning experience.
Oh, and that "900" I mentioned a few posts up was as stock as it could be, it was a nice F1 motor though, and I gave it a good cylinder head with no broken plugs and sold the F1 that I put it in. Edit, later a "stock" K0 engine ended up having a 900 kit in it. It all works out.
