    So I just got my intake back on, distributor stabbed, and got it running, but when I go to advance the timing more, the vacuum advance is hitting the intake. Obviously tue distributor is installed wrong, but it runs fine. How do I get it back to having the advance in the right spot.

    You will have to repull the distributer and reset it. I usually have the #1 Piston at TDC, and then insert the distributer in, making a few attempts (to adjust the rotor) until the distributer drops in to where the electrical plugs (assuming it's an HEI) of the cap will face the 3 o'clock position... then set timing after that... should keep you from hitting against the manifold or carb.

    I would bump the engine until the rotor is pointing to your #1 terminal . adjust your distributor to where you want the vaccum can. look at what terminal the rotor is pointing to and move your #1 wire to that terminal then continue placing wires per firing order.

    If you don't want to pull the distributor you can adjust the spark plug wire placement on the cap. It really doesn't matter which terminal on the cap is #1 as long as the rotor and #1 plug wire are in alignment. Basically you can rotate every plug wire one terminal to the left or right.

    What KEVS said.

    When you move the wires over one do you have to make sure your at TDC first? I'm probably over thinking this but my vacuum advance hits the intake and it's because I could not get the distributor to line up with the oil pump just right. I tried the long flat head trick but couldn't find the slot and didn't want to climb into the engine bay to do it. Sooooo now do I set back to TDC and what way do I want to move the wires on the cap... Clock wise or counter clock wise one spot?

    Find someone young and skinny with good eyes to climb on top of the engine so they can do it. Imagine a Line between # 5 and 7 and drop it in with the rotor just a little ahead of the #1 tower electrode. Helps to put a mark on the base of the Distributor.

    I might be slow but I will get there eventually.
