Day goes from good to bad in one shift

The pulley rotates freely with the belt removed. It also moves up and down and side to side. I need to try and push it in and then try to remove the 15/15" bolt. The pulley is a billet steel variety.

Also pushing the car in gear without the rotor in the distributor turning at the same time..... Sounds like a broken crankshaft to me. I would also venture to guess that the front main bearing is wiped out too. It is now time to pull the engine.

I pulled the oil pan yesterday to see what happened. My original hypothesis was confirmed. The crankshaft sheared between the 3rd and 4th cylinder. Looks like the engien will be coming out this next weekend for some major surgery. I have attached some pics showing what I first found and what is is supposed to look like after I rotated the crank. I have heard about some counterbalanced forged cranks for Model A's. Has anyone had good experience with them?

Thanks, Dave
