I was advised against running a vacume advance distributor in a performance motor. I am running a Mechanical Advance Mallory Unilight and it works like a charm. The vaccume advance is basically for fuel milage and I can afford to loose a few mpg in my cobra as I do not drive it that much. What Distributor are you running? I had bad experience with the old ford distributor in my old 351 Boss Cleveland. The vaccume advance kept getting where it was throwing the dwell off due to inaccurate bushings. You guys ever set points? Old school.

I am running a vac secondary 600cfm holley. The Holley is a temperamental little b!^@h but works fine once you adjust everything.
