Well, who is to say that H-D isn't using the same manufacturing technology??

It's still a pushrod V8, like the H-D is a pushrod V-twin. Granted, both are
using all available technology available today, but pushrod engines still
are so 1900.

Corvette engineers have stated in print that the new Z06 is about at the max
of what they can do with it. And yes, aftermarket tuners can always get more
9as with any engine), but they don't have the constraints of factory
engineers and the fed requirements. Just like what the H-D tuners do with
the V-Twin.

They are both high-tech, carbon-fibered buggy whips.

When the technology finally gets to electronic cams and such for
mass-produced cars, it won't be on pushrod technology. Yes, DC has also
teched-out the Hemi, but it's day in the sun will not be very long, either.

Other than the fancy materials used on the body, there is frankly probably
more technology in the motor even though it's just a pushrod V8.  The
process of how the blocks are made on the Z06 is a pretty cool read, I need
to find the link.  Off the top of my head (been awhile since I read it) the
blocks are initially made 2-3% larger than actual size, in the heat and
chemical treatment that follows it actually shrinks by that same amount, and
even after all the treating and pre-lim work, still like 2 or 3 out of 10
are tossed due to not meeting the quality standards.  The large amount of
scrap is what makes the rest cost so much.  The bores are way thin on it,
using liners, which extend a pretty good ways below the block due to the
long strock (7.0L from a small block!)  titanium rods, and essentially a
dual pump dry sump system (not "new", but pretty trick for a street motor).
Fully dressed the thing is physically smaller and lighter than a BMW 6 cyl,
and will make over 600 chp with a cam swap.

a recent test/article I read from hot rod (I think it was hot rod) called
the heads the best OHV factory heads off any car, anywhere, at any time.

The rest of the C6, is just a slightly washed C5 (1997) with alum, carbon
fiber and magnesium bits...and leaf springs :)
