Rocker arms loosened...crankshaft now turns like a champ. Now, just to get cam and crank both set to TDC and see if the ignition timing dropped anything. I home home-timing this thing isnt too much of a pain...if I have to.
So, looks like the resolution of the chain involved both Donnie's and Steve/Jeff's suggestions. First, the chain was caught and secondly, the pistons were also touching the valves due to dropping a few teeth out of time.
I will keep yall posted - thanks for all the help, guys. Oh, and Donnie...I'm still saving the valve job on this car for you for the late Spring.
