If you have an accurate timing pointer on the top of your valve cover and
add the carefully determined degree marks to the pulley, you already have
most of a distributor machine.  Its called your engine.   By attaching your
powered timing light, you can monitor what your dizzy is doing at any given
moment.  Disconnect the vacuum advance, slowly rev-up the motor and watch
what happens and at what RPM it happens and you then know how much
mechanical advance and when it comes on.  Reconnect the vacuum advance and
repeat the test.

Not the same as a dyno run, no load on the motor, but you can see if both
advance mechanisms are working and how much individual and total advance you
are getting.  You will be able to see any wobble or erratic movement of the
spark timing with RPM,  warning you of worn or sticking dizzy bits.  You can
also recurve your distributor at least as far as deciding at what RPM you
would like to have the advance fully on.

After all, aren't "we tight"?
