Make sure you're using the correct gear for your camshaft. The MSD comes with a cast iron gear with a red warning tag to this effect. If using a hydraulic ROLLER cam, you need to change the gear out for steel gear. It's in the SVO parts catalog.

Take a wire brush in a drill and deburr the gear. Polish it up some.

Put plenty of camshaft moly break in grease on the gear. Put some on the cam gear as well.

I used one medium, and one light spring (if I recall) for 20 degrees centrifugal, all in by 2500 RPM. Static is 14 degrees.

Also using vacuum advance. MSD vacuum advance is not adjustable, provides too much advance, (causes lo load miss at cruise RPM) and has to be replaced with a Crane or Accel adjustable unit. ('57 - '72 Delco). Crank vacuum advance down to 8 - 10 degrees.
