Stock cam 360 idles bad, dies in gear, fixed!

Ok, fair enough. dgc333, my apologies. Sometimes I get caught up in a discussion and kinda forget the main focus. You're indeed correct about idle. But sure as I'm sittin here, I've witnessed the difference that varying lifter preload can do in different circumstances. Comin outta a turn on the dirt track, for instance. It can make the difference between bein a dead dog outta a turn and overtakin the leader. I've seen it....and I've made it happen. With the same car, same combination, same track, same night, in the next round. Is that fair enough? Lastly, I will also add this.....depending on how quickly the lifters bleed down, and how much oil volume and pressure the pump has, it's not impossible for the valve adjustment to have an effect on idle quality. Personally, I wouldn't look at anything and say "no that can't be it". That makes no sense.
