*Help* Engine Locked Up After High Rev

No, can only turn it like 1/10th of a rotation either way and then it just comes to a halt.

Syncro balance weights may be seizing on the crank. You need to take it apart and see what is binding or hitting.

Get some 3N1 oil and Gauss pads. That Fetzer valve is filthy.

I think the turboencabulator is bad.

Is the rod still connected to the piston? in the bottom left pic, it looks like i see the wrist pin hole in the connecting rod.

Also, i wonder if a valve may have gotten bent, and stuck down into the cylinder?

Think I see some carnage on that tappet face furthest from the camera. Rod looks bent down as well. Right there where you put the green arrow. Might be the picture though.

Welp fellas, I've figured out the source of the 'locking up'. One of the valves (exhaust I think) was just chilling there when I removed the cylinder head. You can see in the pic of the rockers where the end of it snapped off and allowed it to fall on top of the piston. I still have to remove the crankshaft and inspect the piston, connecting rod, etc. My question to all of you that know more about this than me is: does my piston look salvageable based on the pics? Is that little notch at the edge supposed to be on the top of the piston? Please give me your feedback/advice here for next steps.

Update* got the piston out. I think it's salvageable. The connecting rod had two small pieces chipped of at the base. It's hopefully looking like I can get out of this repair with relatively inexpensive costs. What's your thoughts guys?

Interesting!. Did the valve just lose the keeper or did the end of the valve break at the keeper groove? I would use the other valve to check and make sure the valve guide isn't fubar'd. I would clean and inspect the piston for cracks. I would replace the valve and rod and FIX THE GOVENOR.
