Hi Rehd,
Chrysler built a dual overhead cam big block V8 back in the very late 60's that was to power their NASCAR entry. They discontinued their NASCAR program before the race season started and the engine was scrapped. It showed up in a junkyard in the 1980's and some lucky hotrodder has a couple of really fancy and powerful, one of a kind engines for his rod.
When the articles were first written on this "new" technology it was experimental. How many of the concept vehicles from the 50's and 60's made it to production? Very few. They were dreams and ideas in infancy that needed improvements before they could be brought to the market.
The reason the 4 valve per cylinder, two sparkplug technology did not come out in the 60's when first reported was for a very good reason which you will see if you look at the cars of today that use this technology. These new cars (they started showing up in the 70's) have more power but are far more expensive to repair and they use MORE fuel!
No one is going to buy a 4 valve engine that has the same horsepower as a 2 valve engine when they have to pay more for it. So the only way to sell it is to give it more power than the 2 valve but then it uses more fuel.
The technology was made feasable when smaller less powerful engines began showing up in cars because the benefits were very noticable. You could have a 4 cylinder engine that performed like a small V8 and had the fuel economy of a V6. You can buy, and have been able to for many years, a DOHC, 16 valve 4 cylinder engine that produces 495 hp. This is the equivilent of the best V8's from the muscle car era. It rev's higher than the V8 and will propel a car faster but it gets no better gas milage. It is not drivable in a street car application and has very poor durability.
Everytime someone comes up with a wonderful new product that will revolutionize the automotive industry they run into the same set of laws that every other new product did. There is only so much energy in a gallon of fuel and any engine of a given horsepower will get almost the same gas mileage. The internal combtion engine is one of the most inefficient machines ever made.
