So, the latest V8 for the Corvette Z06 appears to be quite something. Flat-plane crank, 8600 rpm, normally aspirated, dry sump, 670 hp. It's as though GM wanted to build an engine to out-Ferrari Ferrari. Notable as it's almost certainly the last clean-sheet performance engine the General ever produces.
One detail that stands out to me - the finger follower valvetrain never requires adjustment (!). I am struggling with this a bit. Perhaps the cam/follower/shims never wear (DLC coating), but how is it possible that the valve seats never wear? Or rather, that they don't wear enough within the engine's service life to necessitate a valve adjustment.
Anybody have insights into this?
