I have had funky timing since I bought the truck and finally got around to following the instructions on this thread (
http://67-72chevytrucks.com/vboard/s...d.php?t=258643 ) and others to reset it. I started the truck and began to advance it from 0 degrees with a timing light. When I get to 7 degrees, the vacuum advance hits an intake runner and vacuum port and can move no further. Here is a picture of my setup with the areas that interfere circled in red. Have I put the distributor back in incorrectly? Do I need to change the vacuum advance?
