Uh Oh !! Bad knocking !!

I DID clean-up a rod journal after mild knocking and did sucessfully put in a new Cleavite 77 bearing, and drove the 318 another 15,000 miles with no knocks until I bought a 340 short block.
I know people who used old leather belt sections to replace rod bearings and drove the car another 5 years with no problems, but I'm sure they babied it.
