Why is it pushrod?????? This is meant to be a "new" engine isn't it?? GM could be the only carmaker left still using pushrod engines!

Did you read the article? Its for compactness, its as wide as a V6.

Ford's 4.6L DOHC is wider and taller than a 460ci Big Block, and nearly as heavy in cast iron trim.

Some excellent ideas IMO, most have been leaked before. Not sure about the camshaft in block idea though.

One way to fix the oil pump problems :0

Does it matter where the camshafts are located? What really matters is flow and combustion characteristics and it looks like GM are being real damn smart!

To show tech isn't about DOHC and 4 or 5 valve heads, Mercedes Benz went back to 3 valve SOHC because it was more compact and gave better combustion chambers.

Long live the OHV V8!

The same width as a PUSHROD V6 should be more likely. I can't see how a DOHC v6 with similar stroke, bore and V layout could be any but less wider than the V8.

Aussie Pete, I'd hazard a guess that the Valve Springs will have to push back a fair bit more recipricating mass than the equivalent OHC version, which will in turn either effect the life of the springs, or valve-bounce at high revs.

However, there is some logic to having two cams for all 8 cylinders rather than 2 cams per bank.

Its a interesting engine..

Some what unconventional. Direct injection pushrod. Interesting to see how much per unit it costs.

But lets look at the facts..
4.3L, 300 Hp 295ft/lb.. 3 valves, direct injection, Varible cam timming on inlet.

Should be a alright engine. With it using pushrods its not going to be targeted at a superhigh rever, but most european V8's are more suited to a torquey application. Seeing as how the LS1 does okay with just one cam, no fancy injection and two valves.

Yeah I reckon it does and the problems won't show up for a few years and when they do the engine will need to come out.
