Thanks for the comments. When I loosened the engine to transmission bolts I heard pop. Like something was binding. When I tightened them back up everything turned freely.
Now I have another issue. Once everything was hooked up, I started the engine and nothing but white smoke came from the exhaust. I pulled out the # 4 spark plug and steam came out. It's unlikely that the temperature got hot enough to blow the gasket again since it wasn't run long. Could I have a crake in the block? This is what it sounds like to me.
