Crankshaft pulley interchange
What crank pulleys interchange over the years? Found a few threads that show pulley diameters, but nothing on crank fitments.

The pulleys to the crank are interchangeable through 3.2 with the locator pin to the left side.
3.6 moved the locator pin to the right side. The question becomes which fan belt works with the combination of pulleys and fan Bruce |

So the only difference is the 3.2 pulley has no timing marks other than Z1 and 5

The 3.2 advance is taken care of by the DME
It is marked every 120 degrees Bruce |

What are you trying to do? Change the fan speed or back date the fan pulley? Fan speed and air flow were discussed once upon a time here. Perhaps someone,(Bill?) remembers the thread.
