Is that block straighter than a standard one because of machining? my block is stamped 40 or 41. Were late crate motors straight enough? On some motors is this more for modern amounts of balanced smoothness? And am I ok to leave it till I do my bottom end rebuild down the road? I dont think my car vibrates too much for the design.

Edit: winters coming . probably should do it then
1. The chatter may, or may not come later.

2. No shellac for shims. The shellac is for the gasket, and the 4 flywheel bolts, as the threads go into the crankcase, they would leak oil into the flywheel housing.
3. The dial indicator is in .001 increments. Yes you can split in 1/2 thousandths.
4. I am not sure what you are asking, but I would think all factory pour, and aligned blocks, would be the same.

Thanks,

Herm.
