So I am getting ready to reinstall the distributor off of my 72' 350. I replaced the end drive gear and in doing so came across a few questions. There is one shim that I assume is there to take up some of the end play. But there is still quite a bit of play, I would say at least 3 or 4 more shims worth...
Is this the end play I here often associated with erratic timing shifts? If so what is acceptable? My timing light is a little to premative so I havn't had a chance to check the advance very accurately.
Also, as I spin the rotor and ditributor shaft I feel a little clicking friction. Is this normal?
If the distributor has an iron housing, I like to see ~.005 to .010 inch of vertical clearance; if it has an aluminum housing, I like to see .015-.020 because aluminum expands more than cast iron.
