I have a original 340 in a cuda with about 78,000 on the clock.I got the engine running after sitting for at least 10yrs.It seems to run strong with no smoke.The only thing that seems wrong is that the distributor wobbles too much.What problems will this cause with the engine as in running or damage and such.And is there a repair for this and whats involved.I had heard that there was a gear that could be replaced but don't know much about it.I figured that someone has to have come across this before.Thanks Chris
