We removed the hood, mounted a camera looking down on the air horn, and
took it for a spin, running wide open on an uphill grade. See how the
secondary air valve responds to rpm drop at each upshift of the THM. Also
included is a smoking burnout.

One of the most aggressive looking GTO's ever built the 1972 model was once
again an options package and had a pile of comfort and style while
retaining much of the bite of its forebears. This very cool Lucerne Blue
number retains all of its original body panels, its original 400ci engine,
is exactly as the Pontiac Historical Society documents lay it out and it's
a four speed - that's the way you want one. Great cars to drive these
tigers are collectables on the rise!
Underneath, you'll find an exceptionally clean chassis. This isn't a full
frame off restoration - it didn't need one! Those are the original, clean
floors, rust free frame and original rear end and handling package
suspension. A quick evaluation is all that's necessary to see the original
brake and fuel systems were up to their tasks and required no major
replacement. That's the original undercoating you're looking at! So many of
these cars died an early death it's refreshing to see one that's so clean!
Deep blue paint covers the rock solid, original exterior. The front end is
definitely the best part with its straight body color bumper, excellent
deeply inset grilles and aggressive hood. The GTO exclusive fenders with
rear air extractors add interest to the sides of the car and look awesome
with the mint Rally II wheels and new Firestone G70x15 Wide Ovals. The body
is straight - care taken during its cosmetic restoration is evident. The
trim and chrome is in excellent shape and is mostly original to the car.
Bodywork was minimal and the finish work was done to a high standard. This
is an attractive car with no hidden gremlins.
Comfortable black vinyl seats with new covers are the order of the day in
the restored interior. The sculpted, clean dash pad covers the fully
functional and clean original gauge cluster and nice original engine turned
finish panels. Original door panels with original armrests are very nice,
interior chrome is original and excellent and there's new carpet at your
feet. The factory Formula steering wheel is in excellent shape and feels
great in your hands. The center console with its Hurst shifter is also a
clean original - there are no complaints from in here. The cabin's simply a
great place to spend time!
Open the trunk to find a brand new Wide Oval mounted to a fifth, mint Rally
II wheel. There's a new mat on the floor, the proper jack, new
weather-stripping on the rail and a fresh coat of spatter paint underneath.
Like the interior and undercarriage, there are no problems and no
Pop the hood and find the original, numbers matching engine in a detailed
engine bay. That's the correct original air cleaner on top of the rebuilt
mill. Some liberty was taken with the internals as the compression's up to
around 10:1 and there's a Ram Air IV spec cam to get the power up to where
you'd expect a 400 to be. Those are original chrome valve covers on the
motor, a restored vacuum Booster and
master cylinder on the firewall and a new battery and correct spring clamp
cables tucked away in the corner. New belts and hoses (with correct tower
clamps) are reliable replacements in this excellent driver!
Solid, original body and engine cars are tough to come by. So are desirable
cars with great color combinations and manual transmissions. And, so are
cars which are still affordable! This car's all three and it's only going
to get more valuable over time! Don't wait on this one!

conditions, hope you enjoy.
How to de-bog your Quadrajet part 2
The Rochester Quadrajet has gotten a bad rap over the years, but it's
actually an excellent carburetor once you understand how they work.
Often referred to as "Quadrabog" or "Quadrajunk", many of the issues these
units suffer stem from neglect, or "modifications" that do more harm than
Being a spreadbore, air-valve secondary design, the Quadrajet is capable
of flowing 750 or 800 cfm of airflow, eliminating the need to buy different
carburetors when your set-up changes. In addition, the small primaries make
for great drivability and fuel economy.
In this clip, I'll discuss theory of operation on the secondary side,
since that's where most problems arise. So, leave your preconceived notions
at the door and let's see what makes these carburetors tick.

makes in an effort to improve the performance of this unit.
