Omg, five pages of theory and no one has actually resolved anything. Every engine combo "Likes" a specific curve for spark timing. Sure if you have lots of money you can put the thing on a dyno and figure it out. But for us normal gearheads it's a seat of the pants thing, take it to the track and check your time slips. For a generic run-of-the-mill street car, just buy a good distributor and follow the manufacturers recommended setup.

Time, money, guessing and frustration.... or for $500, you can avoid all that, well, the time, guessing and frustration part and go with a Progression Ignition HEI distributor. No weights, no springs, no vacuum advance pod, programable at idle or on the fly with a host of other features, like going from carburation to EFI, people have to roll with the times and update at some point.

Back in the old days, when distributor "recalibration" machines where plentiful, now only a hand full exist if that, this would have been your best bet to recurve the weights and springs type without it being in the engine.

I saw one for sale on eBay recently and I found it beautiful like an old piece of art. It was affordable too.

I'd personally not bother to dyno-tune an engine. Do it real-world to dial it in. But that's JMO. Dyno tuning only gets you close, and you'll still be doing tweaks afterward. Guaranteed.
