Just got off the phone with the balancer. He had to drill three 1/2 inch holes about 3/4 of an inch deep to get it neutrally balanced! I don't know where they were drilled, but I'll get some photos of it. I'm leaving here shortly to drive to Indiana to pick everything up.

I'm hopeing they drilled these holes in the flywheel. Not the crank...:dunno I'm guessing the wheel. Thats not really that bad. I just wonder whats wrong with the wheel that its needing that much lightening. I can't say if the spin these molds and pour in hot metal or they just cut off a piece of roled bar stock. An air pocket in the casting could be a desaster down the roda. Only an exray or a radio graph will tell you whats going on in the wheel. Could you get a pic of the wheel on an xray table... Doc...:sly
