Presents
This year Sneak
Previews takes a look at GMPP's anounced ZZ572 due to be released
sometime in the near future. GM Performance parts was kind enough to
provide Sallee Chevrolet with both the specifications and a few pitures
to share with everyone.
Ok, we've looked. All we
can say is it's the stupendous! Not only is it a dream big-block engine,
but GM has two versions. One suitable for street/strip and the other one
we can't imagine being used for anything but the race track.
Be forwarned though, you will need your sun glasses when
you take a peek at this beaut. It's BRIGHT red color just might be more
then your eyes can handle at first.
Gm plans to
use the marketing names of ZZ572/620 and ZZ572/720R. I can only assume
that the R in ZZ572/720R stands for "Race" and race it will, that's for
certain.
The pictures provided by GM were not
labled and I have altered them for Internet use. Which one of these two
engines are shown in the pictures is unknown.
Please, do not jam our phone lines, e-mail inbox, or mailbox with
request about when these will be released or what price they will be.
GMPP has yet to announce either a price or a release date. As a rule,
Sallee Chevrolet will announce on our site when these have arrived and
are ready to ship from us, along with the price.
