Rotella diesel oil in a 440 ???

Im with Adam on this,I used to run a pontiac and alot of guys were having major issues losing lobes regardless of cam/lifter brands.After alot of research on my part (with alot of advice from others) the cheapest most cost effective way I found to make them live was to use plain old stp oil treatment.I used it during breakin and every oil change after with no issues.I couldnt beat the price/availability and I never have lost a cam-knock on wood.
