MH, I kinda need to go easy here... I've been experimenting with connies like a madman for coming up on 7 years, and have tried / done all the typical hotrodding stuff - the stuff you're just starting into doing. I don't want to suppress your affinity to experiment and learn as I did, as that's kinda part of our DNA, to take stuff apart and see how it works. If I come off (as I may have already been) as a know it all, it's just going to agitate you, which isn't my intent. That said, I'll offer some info here or there, but basically try not to tell you "how the movie ends" and ruin it for you. with that in mind, I can say this on dialing in the stock cams for midrange - IMO the best midrange doesn't come from any dial in on the stock cams. You definitely can sharpen things here and there with dial in, but the REALLY BIG difference in midrange IMO wasn't borne from cam dial ins. HTH, Steve
