Timed or manifold vacuum advance?

FWIW, I run manifold on my 408 stroker with a 236/242 .544 cam and a Thermoquad carb. Idles with about 10" at 850, and get's 14 mpg hwy through 3.73's and a 4,000 stall Dynamic conv, all on 87 octane (9.6 comp Edel heads) at 65 mph. The vacuum adv is +10 deg, and the dizzy in 16 initial 34 total at 2900, FBO ignition. Car runs 12.20's consistently at 3600 lbs with me, and a best of 12.09 @ 110.

I experimented with a variety of setups and both ports, the manifold works best for my setup. It effectively functions as a timing retarder to ease starting, then adds 10 degrees once engine is idling. Off idle acceleration is smooth at all throttle positions. I can go WOT from idle from a standstill, it flashes the converter immediately, lights up the tire, and goes. Could not ask for a better setup, just need a little more compression, cam and gear.

But then, I'm not sure I would know what to do with a brain if I had one. I just love the condescending arrogance some people put on display, often a cover for ignorance and insecurity. Especially in bold or all caps, accented by gratuitous misspelling. Comical!
