One thing more- you can use a vacuum advance, and I recommend you do so. The caveat on this is twofold:

Use ported vacuum
Use a Crane p/n 99619-1 limiter plate to keep the added advance to about 10-12 degrees (or make one)
Ok, I know ported vacuum for the vacuum advance is hooked to the carb so I'm guessing it is operated in a similar way as the vacuum secondaries, otherwise a motor that has very little manifold vacuum wouldn't be able to operate the advance. If the motor runs well as it is, what would be the advantage of adding the vacuum advance back into the equation? Will it be better for for driving conditions between idle and WOT?
