Definitely... but sort out the centrifugal advance first - THEN add vacuum advance and adjust for light-throttle cruise without surging.

I don't know what attitude your at but unless it is below 1000 FT MSL I would shoot for between 14 to 16 degree BTDC at idle and have all the advance in by 2000 RPM limit the advance to 34 to 36 max,
Set that up first with no vacuum advance and go drive it and then if you want to try the vacuum advance hook it up later so you can judge the results from both independently twocents scope

Down here in Southeast Texas, when I still had my stock worn out 383 in my Charger, it really liked 22 initial, 40 total all in @ 2000rpm, 7 more on vac advance. ported vacuum
