cam selection/cyl. pressure

what I meant was at the sweet spot for the cam, not during a compression test, when the overlap and duration is helping to fill the cylinder more efficiently, it would increase cylinder pressure at that point compared to a cam that doesn't fill the cylinder as efficiently. As socal' said packing the cyl. with more air/fuel thus more cyl. pressure.
Was a long time ago since I set the timing, initial I believe was 14 (that is more of a guess than my next two figures lol) I believe the timing came all in at 2,200, for a total of 34. I set it at 36 and it would ping a little under load so went back to 34 total where it never pings on 91. I'll do a check to confirm this. I had some opinions that my motor was a little under cammed, that's why I was looking for something bigger. Being used to small Chevy's, anything over .500 lift sound like alot to me.
The Demon i set up from the jetting info on Demon's web site, then left it alone. It makes WAY more power than the vac. sec. Holley I had on there that was prepped by a shop, but maybe a lean spot at part throttle? (over half) Oh ya, I have a MSD billet distributor with no vacuum advance and a 6A box.
