Dyno tuning ?

I'd start out with a stopwatch and a stretch of country road.

Run from 2000 to 5000 RPM in 2nd gear. This allows a good load on the engine, should eliminate wheelspin (mostly) and keeps the top speed down.

Do the timing first, vac advance disconnected and plugged. Advance 2-3 degrees at a time until you quit going faster or get detonation. Write down the setting and air temp.

Then do the primaries (disable the secondaries) go up 2 jet #s until you quit going faster. Then hook the secondaries back up and repeat 2 jet #s up until you quit going faster. In either case, you shouldnt be too far from the out-of-box settings. Don't be surprised if you can actually go a step smaller and not slow down. Don't forget to keep notes!

This is a whole lot cheaper than dyno time, and should get you close. Heck for what a couple hours on the dyno costs, you can probably pay for several nights of "test and tune" at your local track.
