I give my lefty for a twin cam in the garage Deano...
This one was came up about twelve months back, from and inland town in the South West of WA so it would've been sitting in freshwater, it popped up on gumtree for a day, he obviously had some interest in it so it went to ebay apparently.
It was a complete car engine, interior, the lot but was almost broken in half from the rust and when they pulled it out of its resting place with a piece of earth moving equipment. I wish I'd saved more pics of it.
I heard from a reliable source it went for around 20k.
