Any idea why the cam assembly doesn't want to come off the shaft? This is for a 1972 Motorcraft, if that matters. Yes, the circular retaining spring came out. I already disassembled the '67 dizzy, and that had no problems, it lifted right out. On this one, It will rotate fine (within the limits of the advance limiter boot), but it will only go up and down maybe 1/8". Is there a distributor change between '67 and '72 that I'm missing?

Yes and yes. Everything is apart except the cam assembly and shaft. And of course the thrust washer that sits under the cam assembly.

They sometimes are very hard to get off. First pour penetrating oil in the cam cavity around the shaft. Let it set four a few hours. Next try prying gently under the cam on two sides and down on the dist. housing with two screwdrivers. Do not use too much force and distort your housing. If this doesn't work, you have to use a special puller that pulls them off.

Already tried overnight with the PB Blaster, and some gentle prying... no luck. It's currently soaking in Simple Green, which should loosen any grease/dirt. If that fails.... Heat gun?
