[QUOTE="Gilaguy23, post: 436211, member: 19498"] Yeah somewhat. Most hot rodders advance timing until they get a pinging or predetonation. Thats also on a engine of various hipo mixed parts and no "manual" setting really applies. Octane ratings, elevation, and engine are all factors. In you case frankly running the best you can get it to run is moot as the smog shop needs to see 6 BTDC or whatever you 258 is supposed to have, or it will fail. I once live in commiefornia where the state smogged your vehicle. You fail you go to a mechanic somewhere else where they "fixed" it. Then back to the state smog inspector again. Back then you fail to many times and your dubbed a "gross polluter" and your screwed. Be aware of your states BS laws and Im guessing CO is no better than CA anymore. [/QUOTE]
