The cat launching trebuchet sounds like a good one.

I’m gonna build one not for launching cats but I want to build a trebuchet. It can just sit in the yard.

Thanks for the help with the head ID.
Considering I just pulled the original PCV valve out of this truck, I'm not too worried about cracked heads.
