so while i was tuning up my truck i tossed the stock air box because the vacuum lines were all mangled and it was beat pretty bad, i wasnt sure how to run the vacuum advance, right now its T'd off to a line that connects to carb. hows everyone else running their advance with an open element air cleaner? off the carb? manifold? its on an 86 GMC jimmy with a 305 and 4 speed. thank you.
