- Cylinder wall distortion can lose a lot of power. The Cleveland is
- infamous for that problem.

- By the way, I was reading a 1940 edition of a 1912 automotive guide
- this morning. There was a long section on cylinder boring, including
- interesting machines that would bore the block while it was in the car.
- Then it started talking about how the cylinder walls will flex slightly
- under the boring bar, which doesn't hurt anything if you're boring, say,
- a piece of pipe, but engine blocks commonly have upper and lower water
- jacket decks, head bolt bosses, siamesed cylinders, etc. They explained
- how these areas didn't "spring", thereby causing low spots as the bar
- passed. The book then talked about reaming cylinders to size, which
- they claimed had the same problem. (the thought of a 4 inch diameter
- reamer is kinda interesting...) They felt the optimum solution was
- *grinding* the cylinders to size. Sounds quite reasonable, and I think
- they have a point... except I'm not aware of any place currently selling
- a cylinder grinder. (Anyone?)

- Yes, but a few years ago those blocks were $1800, not $665. As for the
- mains - have you spun any bearings with the two bolt block?
