Parts book shows to be all the same part # as with the drive gear. I would have said no but the parts book would have proved me wrong. Guess they designed the engine around the distributor dimensions ! Go for it.

That was, of course, the sensible thing to do; therefore it is amazing that the design engineers chose that path! TongueWinkLOL

One notable thing between the two engines is/was rated speed was 1650 RPM and the high idle speed was 1950-2000 RPM. So, the advance mechanism should have been the same.
