CM400 Engine Seized; how do I rotate to get cam chain off?

[jrocker3235]

So I picked up an '80 Honda CM400 for $250. The guy said he heard a clunk and the engine just quit. I started tearing it apart and I got to a sticking point. I took one bolt off the cam chain sprocket but I can't turn the engine 180 degrees to get the cam chain off cause the engine is frozen.

Please if anyone has any ideas, I really could use some suggestions. Thanks!

Last resort, I will cut the cam chain and just buy a new I suppose.

Put a rag under it and cut it with a die grinder it toast anyway

Break the chain. It's not rare and should be replaced anyway.
