As others have stated, the cam/springs combo is important. But, if you're just looking for VERY accurate data concerning the ZDDP of common oils, this thread is a good place to start. The data is about 3 or 4 years old, but I doubt that the concentrations have changed much.

I have factory pattern 383 HP and I just use whatever, usually Super Tech 15w-40. Sometimes I try straight 30, 10w30, 10w-40, it doesn't seem to matter that much. However, the original valve train is nothing extreme.
If I had the current aftermarket steep cam and high spring pressure, I would be a lot more cautious.

Myself I have used Valvoline oil since I started working on cars in the early 70's. When the VR1 racing oil came out I started using it and have used it for years. I have never built a roller cam eng for myself as all my engines have been and still are flat tappets. And knock on wood I have never had a cam wipe a lobe. Course I do make sure everything is working right like making sure all the lifters are rotating and so on. Right now I am running the non synthetic Valvoline VR1 20W-50 racing oil which I usually run in all my engines. I have always had great results with the Valvoline oil so stick with it since it has worked great for me all these years. Ron
