So how do some of you play the 'dwell game'.
We plan on paying more attention to the details this time.

Dwell angle is the number of degrees out of a full rotation of the distributor that the points are closed. Look up the recommended setting for the engine being serviced.
A Ford Y-block is 26 to 28.5 degrees. The dwell on the points can be set with the dist cap & rotor off while cranking the engine over with a remote start switch.
I usually set the dwell at the 'wide' end of the spec. so the points settle in to the middle of the range as the wiper block gets some initial wear. Put a very small dab of dist lube on the cam lobes.
Once set, the dwell should not vary by 4 degrees or more when the engine is running. If it does the shaft bushings are too worn.
Also make sure the centrifugal & vacuum advance mechanisms are clean, very lightly lubed (as needed) and working correctly.

After the points are set then the timing can be adjusted. Y-block engines usually like a few extra degrees of initial/static timing.
If you're looking for better performance an electronic conversion kit to replace the points will make the ignition more stable (no 'points float') but won't add performance on its own unless other more expensive changes are made... depending on what parts you're starting with. (upgraded: cam, valve springs, heads, intake and exh manifolds, etc. etc.)
Which might shoot down your stated "On A Budget" premise.
