This car is begging for a gear ratio change to get that RPM below 2000. You will lose the "wonderful power", but won't need that power once you get good at DWL.
As for ignition timing, look for a Haynes or Chilton repair manual. You can lose several MPG if the timing is off by only a few degrees.
Cam timing is not intended to be adjustable. It changes when timing chains wear.
Does it have a carburetor or fuel injection?
