First thing I would do is turn the crank over by hand to top dead center, then move the crank back and forth to see how much the distributor moves if any-that will tell you if you have any chain stretch, and also while it is set on top dead center make sure the distributor is set at #1 cylinder,if not then the chain has jumped. If all that is ok then move to the wires and plugs,at least try changing the #2 wire and plug if that seems to be the only cylinder that changes when you pull the wire. You indicated that all looked good with the rockers and pushrods-do they all look like they are lifting the same height while running? Try spinning the pushrods by hand to see if any look bent. Most likely if the timing has jumped it wont be running at all. I had an old Chrysler 300 many years back that I bought and drove home, but that was the last time it ran as it had jumped timing and wouldnt restart, even with 3 people trying at the same time:toothy10: 1 cranking,1 moving the distributor and 1 working the carb. Keep us informed as to your progress as it is very hard to help/diagnos problems without physically being there to help.
