So, I'm trying to tune my 440 in my 72 Duster, I see the vacuum advance is not hooked up and do not know if it is locked out. HOW can i tell? The motor has the MP 284 cam, headers, Airgap intake and 750DP.
Once I figure out if my dizzy is locked of not, where should my initial timing be?
From here I need to schooled... who has a Ignition timing for Dummies lesson?
