Are these cracks in the crankshaft rod journal? I am not a machinist, I don't really have much experience or expertise with this sort of thing. I will try to get this to a machine shop when I get a chance, but any insight would be appreciated. This is a cast crank from a Chevy 350. I had planned to put together a decent little 350 to run for a couple of seasons in a Chevelle. It is not going to be used for racing. Just a nice strong little engine to run until I can get a big block put together. I was thinking something like a 325 to 350 h.p. 350.
The pictures are not that good, but hopefully you can see the little marks on the journals that I think might be cracks. There are also lots of paper fibers on the journals, I used a paper towel to wipe the crank off.
