Nope on the 4 cams, 4 valves, and VVT, and of course, it has pushrods. That doesn't mean it isn't sophisticated, and it doesn't seem to need that stuff to make plenty of HP while delivering comparatively good fuel economy (17/24 mpg). The basic specifications are the same as Le Mans winning C5-R engine. 7.0L, 505 HP, 470 lb-ft torque. Aluminium block and heads, and you don't hear Corvette owners worrying about hitting the 7000 rpm redline with this motor. Titanium connecting rods and intake valves, sodium-filled exhaust valves, 11.0:1 compression. Dry sump lubrication.
That's a lot of engine for $14K. Considering that Porsches with comparable performance have engine replacement costs probably in excess of $30K, owners should expect at least similar performance, efficiency, and reliability than a Z06, and reasonably, should expect a lot more.
