Its hard to argue with real life results like that. So, whats your take on Zinc additives for early SBC motors. Fact or fiction or is somebody really getting rich? I ran Brad Penn racing oil for a brief time in another hotrod years ago. Those guys (Brad Penn) in NW PA swore up and down they had found a vein of oil that was rich is zinc straight out of the ground. I know why its "green" in color.
