vacuum advance. When you floor it, the distributor will advance time for more power. The hoses need to feed off the intake somewhere. I think you can get a fitting that will splice off the brake booster hose attachment to the intake.

A good test to see if vacuum advance is working is hook up a timing light, start the motor, aim it at the timing mark on the crank pulley, and give the throttle linkage a good tug. the crank pulley should advance away from the timing mark and go right back to normal when you let off the throttle.

you want it hooked to ported Vacuum off the carburator. If this is the Holley in your Sig ported vacuum is the port on the side of the primary fuel Block.
