can adjustable vacuum advance be added to any motor? my 460 is using all the stuff that came with the 79 when i got it, we just put it on the 460. whats the advantage of it besides the adjustability factor? AXE
The vacuam advance is used for " gas mileage " and you would adjust it if you get any knocking at a steady speed provided everything else is set right. You could also try adjusting it up if there is no knocking.
