Scored a Mirror 105 engine. put on engine stand, knocked the engine down to just bare block. put it in my truck to take to engine shop and sometihing fell as I was unbolting the block from the stand. picked it up and it was a piece of the block where the starter bolts up. Found someone who said they could repair the block for $500.00. Anyone ever have to repair this typoe of damage? anyone run the engine without repairing this? bolt starter to bell housing without block support?
