The official FABO machinist/member collaboration, busted 340 thread
Well, after cleaning the block, we decided to run a hone through the bores real quick to see if it will clean up with a additional .010...(at .030 over currently) . I am not sure you can see in the close up picture, but all the bores are heavily pitted, I dont have much confidence in ending up at .040 over with a nice bore. Looks like perhaps .060 to clean up. Very obviously a rusted up old .030 over block just honed when last "rebuilt"
