Free 77 300D NA head and block
 

I pulled the head off the trashed engine I had. It melted a piston, so one cylinder has piston bits on it. But the engine turned over easily by hand before I removed it. Hate to junk it. Only catch is I won't ship it. You must pick it up. You can have the block to, but again I won't ship. The block doesn't have much of a ridge at the top. I can barely catch my fingernail on it. I'll get some pics posted later today.
