Ls5
Found it over on ls1tech:
Per Autoweek:
Three- Valve Power Boost
If you think car companies have been spending all their engineering talent developing
hydrogen-powered fuel cells or dilithium-crystal hybrids, think again. General Motors
unveiled a 6.3-liter V8 with three overhead valves per cylinder (one exhaust, two
intakes) that makes 470 hp at 6700 rpm and 385 lb-ft at 5600 rpm. Engineer Fred
Rozario says the extra valve increases horsepower by 13 to 18 percent over a two-
valve engine.
Gm is not saying where we will see the engine, but the small block is ready to go and
could be adapted for car and truck applications.

volkswagon had that a while ago, and GM's Saab division had 5 valves per cylinder years ago, not really new technology, unless they make it reliable (the odd number valves tend to have high valvetrain failures compared to even numbered)

I'm all for pushrod engines, don't get me wrong. They are a lot easier to work on, but GM needs something to get them out of the slump they are in. They are trying with the new warranty program, but thats only a drop in the bucket. I would HATE to see them taken over by some foreign pinheads who would change the entire line-up to 3 cyc 50hp compacts..
We 'true American's' love our big displacement engines...those no replacement for it!!
