I purchased a new 383 stroker crank from ebay. These are the numbers stamped in the cast, on the front counter wieght: LYO 408 OT 350375 OCL 1855. Do they mean anything to you guys? Good? Bad? Anything I should know. They said it is a new nodular cast iron 3.75 stroke all std main and rod journals.

 

WAG the 350 means it has 350 size journals and the 375 means it has a 3.75" stroke. the resr could be where or when it was made. you should of worried more about what it was before you bought it not after.

 

I had a machine shop look at it, and they said it was cool. I just thought the numbers may have meant something. thanks.
