I was about to say that you would not have a broken timing chain if the
distributor is turning, but then I stopped and had to think, is the
distributor powered off the cam or the crank? I'm about 99.99999%
positive that its powered by the camshaft. This goes to show that your
timing chain is infact intact. I suppose its possible the chain could
have jumped a tooth or more... On both my old 3.9L premags, he timing
chains rattled around so bad that it was almost possible to pull the
chain off the sprockets without taking the sprockets off the cam and crank.
As other have suggested, pull the plugs and see that you have
compression at all cyl's
