    Pull the valve covers and read the cylinder head casting numbers.
    They should both be the...
  9. Re: Distributor gear worn in strange manner?

    Great point.
    If the distributor housing's lower bushing is heavily worn on the one side, the two gears will want to separate, possibly causing the unusual wear pattern.

    Mark, can you explain the math and how that works out to be at/near .083" after one full turn.
