With my current cam, I find it idles a little rougher than I like. I also don't have any vacuum hookups besides a pcv, so that's not an issue. And I don't know what it's currently set at, although I think its advanced at least some. What does advance/retard do to the engine? Would retarding it some give me a more streetable combo? My overlap with no advance is 72, which is kinda high already. What are the extreme adv/ret settings I should use? Thanks for all input. graemlins/beers.gif
