If your interested in stock timing that is one thing if your interested in timing for best power thats another thing. For power pick up a Mr. Gasket or Moroso or Accel distributor weight and spring kit. Dont use the weights in the kit just a set of springs. Hopefully you have a dial back timing light. You want total timing with vacuum advance disconnected of 36 degrees. If you hear no pinging when accelerating, regular is fine.
If you just want a stock spec. try 9 degrees BTDC.
There are tons of things you can do for power starting with the above dist. modification. Headers, aluminum intake, carburetor, performance mufflers, etc.
