I screwd my motor when my balance shaft went crazy, it ate a hole out in my block. Can I use a block off plate or do I need a new core? I found a 2g with a spun rod bearing for $75. I want to use my rotating assembly since i have forged pistons and cryo-shotpeened old 1g rods. Will my stuff bolt in, if not what do you guys think is the best way to go?
