Is it knocking or clanging? Knocking is likely to be rod knock from a bad bearing. Clanging is more likely to be from a chain hitting something. Maybe the tensioners were installed wrong. A chain could be off of one edge of a sprocket (duplex chain installed on one edge instead of both). Of course these are only guesses. You probably need to take it to a shop that knows these engines to have it checked out.
