I currently have it hooked to timed vacuum according to edelbrocks picture. This is where I had it hooked prior to the fire with the old distributor still in place. My carb is the same carb just rebuilt, the only thing that changed has been my distributor. At idle with the old distributor in the same vacuum port as it is in now it would take my timing beyond where I was able to see and it ran great. I do not have a dial back timing light. With the new distributor I get no difference in timing at an idle with the vacuum hooked up and it just doesn't have the power it did with the old HEI.
