Interesting. The new GM V8 for the next generation 'Vette will be camless with infinitely variable valve timing. How cool is that!
Now comes for the engines. This is the only part that the automotive magazines have totally gone wrong on. Here are two things that the C6 will not have for an engine: One with displacement on demand, and one with two cams in the block. Rumors about these two features have been plastered along side every C6 story we’ve read, but they are simply not true. But truth can be stranger than fiction as you will soon read. The base engine, dubbed LS2, will be based off the current LS6. It will retain its 400+hp status and OHV layout. Expect improved fuel economy, and performance (mostly due to the reduced weight). The strange part comes strait out of aviation history books. The high performance version of the C6 (possibly still named Z06) will be powered by a new generation of cam-less engine. That’s right, electronically actuated valves. Not only will this give the HP version of the C6 infinite valve timing, but close-to, if not north-of 500hp. Cam-less engines have been used for years in circular piston aircraft engines where placement of a cam is impossible. Since publication-we’ve gotten wind that this cam-less engine may not be available at the start of production-despite the fact that Dave Hill has promised all 3 versions at the start. Snake tamer is one word we look forward to using with the C6. This little bit of engine information has already gotten close to 14 people fired from GM, and is one of the C6’s most closely guarded secrets.<HR></BLOCKQUOTE>
