line hone of block, question
line hone of block, question I am looking at purchasing a block. The owner says it has been line honed and measured 0.0005" oversize. Is that acceptable, does it require special bearings, etc.? I did a search for main bearings, and the only things I found were in reference to the crankshaft (undersized bearings).
The main housing bores are supposed to be 2.7509"-2.7515". If the mains are .0005" over the low (2.7514"), you're okay. However, if the mains are .0005" over the high (2.7520"), that's not okay.
The diameter of the housing bores is what keeps the bearings in place. I don't know if .0005" is going to cause a bearing to spin, but I wouldn't want to test that.

That seems like a very tight window to hit, especially with so many people having their block line honed, not to have options (larger bearings) if the mains were 0.0005" too large.

If the machinist goes over too much, he'll just cut the cap where it meets the block and the bore is undersized again.
