timing question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I finally got a timing light and checked my timing at idle. Looks like four lines to the advance side? If each line is two deg. that means it is 8 deg. advanced? Is that about right or what? Daily driver stock 350 holly carb 45 gap on plugs.

Thank

10-12 usually works good on mostly-stock 350's
