Default Bob weight of stock LS1?

Can anyone in here tell me what the bob weight for stock LS1 needs to be? I would like to be able to drop a 6 liter crank off at the machine shop and just tell them to balance it with "X" amount of bobweight to make it within factory balance specs for a LS1 with stock pistons, rings and rods.

Don't think it'll work, as assembly line engines were never "balanced". All your component weights could vary to an extent beyond your balance shop's tolerance and will need to be brought to the same weights. If you're gonna spend the $$$ to balance, do it right.

Agreed. Each mass produced component is built within a weight spec. In order to balance it right, you will need your entire rotating assembley, including, rings and rod bearings.
