MSD E-curve Distributor Set Up???

FWIW, I run a FBO recurved mopar distributor with 16 inital, 34 total mechanical, and 12 vacuum.

Starts easy, idles good (would like 20 inital, though!), and the ET/MPH (best of 12.003 @ 111 mph) are best at around 32 to 34 total.

The Vacuum is great for cruising and highway. With my 408, a well tuned Thermoquad, 3.73 Dana, and a 727 witha 4200 stall convertor, I would routinely get 14.5 mpg. Now, with the switch to a TKO 600 with .64 overdrive, I have gotten as much as 24 mpg. So, IMHO, the vacuum advance is great for economy. Mine likes it, and I can definitely tell when it is disconnected. And once you go WOT, the vacuum drop to close to 0 anyway, and no vacuum advance.

Oh, and I've been looking at that same MSD distributor for some time, just have not been able to rationalize it. Yet...
