wear time est?
 

From looking at these pictures can anyone give me an educated guess as to how many miles are on this engine. As you can see, it still has highly visable hone lines. There is rust on it because it's been sitting for over a year. These were taken from the bottom of the block.

Also I was wondering if this wear pattern for the main bearing is a bad thing. I am replacing them, but is this normal?
