the eagle cast cranks balance very easily because they leave out critical weight in important places on the rod journal side of the crank, particularly the front journal overlap area, seen quite a few break in extremely mild engines



I noticed this very thing when I had my machinist balanced my crank. He didn't seem concerned though... But they are scary thin in spots. Hope mine doesnt grenade soon So far so good though I wonder what happens when a crank breaks like that. Maybe it's not as bad as a thrown rod
