Looks as messed up as a football bat! Surely all the R&D GM has to spend on the advancement of the next generation powerplant, they can do better than this. Look at the return on investment on the LS1 family GM has now derived in their trucks after developing this series first for their corvette powerplant.

I'd like to see how the intake valves are adjusted. There must be an adjust under each valve. What I can't understand is why domestic manufacturers have resisted for so long going to overhead camshafts.... ?!

I've seen the schubeck engine before... but it's a limited production unit that I'm sure parts are waaaaay expensive. What ever happened to the Falcon engine that was supposed to hold so much promise. After all.... they had a patent on the thing. Ever been to the USPTO site and seen some of the bull**** things that are awarded patents? It just seems weird that so many domestic builders are still pushrod. Not that pushrods are bad.....

Hot Rod - June 1999
Jim Feuling's first prototype for a three valve head, two intakes, one exhaust, centrally located spark plug. Never heard about it again, but the idea was better breathing without insane valve train specs, and avoidance of hot spots and resulting detonation caused by the difficulty of cooling between the two exhaust ports. Very smart guy, worked on the Aerotech porject for Oldsmobile, many other manufacturers.
