‘70 C10 Ignition

[broberson]

Call me ignorant, but I’m curious. I currently have 24-26 degrees of advance on my crankshaft, and the vacuum port on the distributor is hitting the manifold. I know the orientation of the distributor needs to be toward #1, but what if I were to remove the distributor and replace it without moving the crank until its seated, in order to get more clearance for the vacuum? Not moving the motor seems to me like everything would stay the same, just wanted to get differing opinions.
