Data Point on Factory Balance

[nm9stheham]

Machine shop called this afternoon...he had spun the crank and showed it need weight added to counterweights....wanted to know what I wanted to do...external or internal balance...I replied internal.
The front counterweight needs 130 grams and rear needs 113 grams...should be ready in the morning..

Thanks. Are those the weight of the added weights themselves, or the net added weight?

When you get it back, would you mind posting a couple of pix of the weight placement, and if you can figure out the dimensions (length and OD) of the weights?

When to pickup rotating assembly this morning and the machine shop said they were wrong went they called me.....they had to remove weight from the crank....lighter pistons and rods then the last 408 I had balanced...where they added a small slug
