Would like some opinions on this LS crank I have. I pulled it out and 3 of the main bearings had deep scratches through the middle of the bearings. It would be going in a high hp turbo build and I have terrible luck finding a mint LS crank. Tell me what you think.

 

I would take it to a machine shop, maybe have them polish it up and mic it. That will tell you what you need to know. It will probably be fine, but 99% of people on here would probably say "junk"

 

I have a spare crank, should be an ls, if i remember. If it's junk, let me know if you're interested. Otherwise, good luck with yours.

depending on the depth of damage the machine shop will either polish or regrind. if the journals are original (never been reground) then size change should be minimal and oversize bearings should be easy to find.
