So things went bad yesterday.  I have a a 292 that at some point was rebuilt, was running great until yesterday. 
    I am driving along, not goosing it or anything just, cruising.  Halfway up a hill there is a pop and it goes dead.  In fact I didn't know the engine died at first i thought it popped out of gear.   Tried to turn it over, it turned over fine then it but would not start.  I'll skip to the chase rather than explain all other troubleshooting.     It turns out that the distributor shaft was no longer spinning when as I turned the engine over.  It also seems the that housing spun a bit and dented the firewall with the advance canister.   Two and half hours later I am on my way home in a tow truck.  I have not gotten into it much, but here are the facts.

1. The engine turns over,
2. I pulled the valve covers, (understanding that if i broke the timing chain or cam, the valves were already done for from trying to start it on the side of the road.)  and turned it over, all of the valves move. that says to me that it isnt the timing chain and if i broke the cam it is all the way at the end?
3.  The distributor shaft would turn by hand, but only the normal amount, i guess it is the amount the mechanical advance plates allow.  
4.  the distributor did not want to come out on the side of the road, i could not rotate the housing or pull it out.    by the time i got it home and turned it over to check the valves i could turn the housing just a little bit.  

So it seems like I broke it pretty bad.   I would like to try to get the distibutor as there will clearly be evidence of what happened either by a stripped gear, or something broken near the oil pump spade part.   Then with a flashlight i guess i could see if the gear on the camshaft is turning or not, or if it is stripped or whatever.     I know in many many ways the dammage is done and I will deal with it, however if there are thoughts or advice I would love to hear it.   I would hate to cause more dammage while pulling the distributor out, but i am thinking that still has to be step one.   I dont recall but i dont think there will be anything to be learned by pulling the intake a valley cover, there is no access to see the distributor and cam gear ...right?  she had been runnin like a top...
