So was the 917 a DOCH? The cutaway seems to show two camshafts, but the bottom shot looks more like a 911 chain setup?
If yes, funny they never went into production with a DOHC 911.

That's not a true 917 cutaway, a 917 had a gear based setup ![]() the bottom pic you refer to, that looks like somebody trying to figure out how to make a 917 like engine with efi Not a good setup if you ask me , them camshafts are very long to be driven from one end only.

That motor was designed by someone with a dream to some day put it into a 917 replica. Not sure if it will ever be built. Found the pics on GT40s.com

![]() ![]() all taken a few hours ago with my pathetic iphone. Me the the old dude with the Jack Olsen pose. Local hot rod P-51 I'm trying to snag a ride on. Heard this beast from 8 miles outside of town on a calm night. Second to last pic some cool rich dude checking it out probably going to buy this sweet beast in the next month or so. Some of our local oil barons are chunking their toys.
