I personally know guys that have wiped cam lobes in their Mopars. Not fun.
Last cam i installed was when I helped a young guy install a Comp cam in his Ford 351. Comp stated right up front that the warranty was void unless you used their break-in oil. So we did.
There is no doubt that modern oils are formulated with less zinc.
Like the old commercial said, "you can pay me now or pay me later."
Your choice but I don't want to chance it. I remember the days when I could get a Fram filter and 5 qts of Valvoline for 5 bucks.
