Long story short: stock 350, small B&M supercharger, 600 holley. Trying to get it tuned and just cant quite get it. Plugs are showing super rich. Pops out the exhaust when you back off the throttle. Seems to want a ton of advance. Im way off the timing tab before it starts to run good. Id try to go more but the vacum advance hits the supercharger body. I could re-drop dist if need be. At zero on the tab it runs like ****. I guess a question would be: how can this thing be so rich? I figured with the supercharger im jamming a ton of air and if anything id be on the lean side. I guess im looking for any thoughts, opinions.
