Need Opinions. Have nothing to compare to.

That sounds great.
Perhaps with a blower, having a warning setup is good idea. I think in your situation its going to be too coarse and a distraction. If you hear pinging at WOT, that's the one situation where you need to get off the gas because the engine can be damaged. (The spark plugs will also show even light detonation in the form of tiny speckles of metal on the porclain).

Glad to help. Its always good to help someone who is as interested in learning as you are.
I meant to mention my favorite books on carb basics are the ones written by Mike Urich. Either the little one on 4150 Holleys or Holley Carburetors and Manifolds. Used copies are pretty cheap.
On-line, Chrysler's 1970 Carburetor Fundementals and Facts is pretty good. (Just note that Holleys vent to the air cleaner whereas Carters are often vented to increase pressure in the bowls.)
Another Chrysler booklet from that year gets into the basics burning of the fuel.
I can't think of any great overviews of the ignition timing concepts, but this page showing the piston position and these on purpose of centrifical vs vacuum advance
basicly cover it.
