Advanced? Its an average modern v6. Apart from VVT, there's not a damn 
thing to distinguish it from any other (and most others have VVT these 
days, so even that's not distingui****ng- some have VVT and cylinder 
deactivation).

And if the hear really were iron, then it would be exactly as advanced 
as the 1962 die-cast aluminum block/iron head slant-6.
