Lucas has exactly the oils and the zinc aditives we are looking for. I was given a sample of the Zinc additive recently plus a brief description of the special oils forf lat tappets they have in stock. I see comp cams and a cuple of other companies will nitride cams for the buyer. Worth considering i think. Some cam companies have had trouble for years. Now they have found an excuse. We have little trouble (like none that i can think of right now.) with regrinds when we are doing experimental stuff and using old factory cores.That makes me a bit suspicious that it might be more than the lack of zinc Don [Non-text portions of this message have been removed] ---- Please address private mail -- mail of interest to only one person -- directly to that person.
