An eBay seller in Sydney, Australia, offers this wooden engine. Presumably it doesn't function. From the description:
The entire engine, including the manifold is handcrafted out of wood. The engine is based on the Ferrari 365GTB V12 engine. It's about the same size as the original engine and weights about 25kg or 50lbs.
There are ten more pictures at the link.
