Years ago we used half STP and half 50 wt motor oil, but that was when oil had good stuff in it. Now I use regular assembly lube, usually Permatex brand. As mentioned I like the cam manufacturers brand of cam lube and I coat the heck out of it. Just as important I think is to add a quality break in additive into the first or even second pan full of oil. Oils anymore are lacking so much of the good stuff you need all the help you can get.

I don't think anyone yet has touched on the importance of prelubing a new engine with an electric drill and appropriate luber. I have one I made for Fords out of an old distributor with the gear ground down, and one I bought for Chevys. I usually run the drill until it gets too hot to hold. So far so good, no cam failures to date. (oh oh, now I've jinxed myself! )
