I just put a Delta RV cam in the 2.6 I rebuilt. While the truck idles great, with very slight valve tick, at 8 and 8, I called Delta yesterday and they said 8 and 10. When I do the first oil change, I'll probably readjust the valves and see how it goes.

I have a load ping and black (sooty) #1 plug, but that is unrelated to the cam. A lack of power has me thinking EGR system, but you don't have that problem, so...
