The 5 sets of rod bearings were from a reputable engine shop. I had a fresh block bored and it still ate the bearings (this is the block I was using when I spun the bearing) The only thing left to replace with the other rotating assembly was the crank. The plan was to have another crank balanced with my good rods and pistons. I had it at the builder for like 4 months and they were to busy so I decided to pick it up and throw old parts together. It didn't work out but neither did "doing it right"
