Built to showcase our new Tri-5 replacement
chassis, the GT55 project was conceived
during a conversation with then Super Chevy
Editor Terry Cole and Publisher Tim Foss at
the 2002 SEMA show. At that time, the
chassis only existed on Art�s CAD system as
a few rough draft drawings and a business
plan that I had drafted. To get the project
into full swing we needed to design and
build a prototype chassis, design and build
a jig table and numerous sub-assembly
fixtures, build a production frame and start
working on the car so we could begin to meet
editorial deadlines!
Art�s 1955 Chevrolet 210 Sedan had sat
collecting dust in the garage for nearly 8
years. It was always a project that we �were
going to get to�, but neither Art nor myself
had any definite plans for the car. There
was talk of building it into a hot rod and
fabbing in a rear clip and putting in a 502
with a four speed. Now, that the new chassis
was on its way and Super Chevy was covering
the action, the old Chevy was brought out of
mothballs and we had a real focus for the
build. While we wanted a car that could
perform out on the track, Art also wanted
something that was comfortable to drive long
distances. There was a lot of discussion
about what we wanted as a final product and
were discussing a project name for the car.
With some searching I found the definition
of �Grand Touring� on autorepair.com. ��A
car combining sedan and sports car features
in which engineering is the dominant
feature. Combines excellent road handling
qualities with relative comfort�.� This
described our goals perfectly, and the GT55
name was born.
The first stage of the GT55 build-up went
relatively fast. With the stock trim, glass,
paint, interior and wiring all there and in
decent condition, we just had to focus on
the chassis swap, and sorting out the new
drive train and cooling system. In this
configuration, the GT55 was the ultimate
sleeper car: killer suspension, a high
horsepower Bill Mitchell small block and a
bulletproof T56 6-speed from Keisler
Automotive and a faded, crusty paint job. In
the weeks before testing was to commence,
Art flogged the car to reveal any weak spots
before its big test, which was to be
conducted at Fontana, CA in October of 2003.
The GT55 was beginning to show its true
Grand Touring soul when we drove from
Tacoma, WA down to LA for the �Road Rage�
tests. Even at triple digit speeds, the car
was smooth and tame. During the trip, both
Art and I were wondering just how well the
car would perform. While we weren�t sure how
the car was going to do, Art and I were
blown away that the GT55 produced a 0.94G
average on the skidpad, and a slalom course
of 48.37 MPH. This was a record that stood
for nearly 2 years.
With the testing over and the mechanicals
sorted out, it was time to perform the
cosmetic transformations. In December 2003
the disassembly of the car began. From
January to July, the thrash was on.
Somewhere along the way, the project began
to snowball and the car went from being
�just a driver� to a detailed show car.
Sixty to eighty hour weeks became the norm
as Art, myself, a few friends, the guys at
Byers Custom & Restoration and McFarland
Custom Upholstery all worked together to
complete the project. There was just 12
hours to spare before it was loaded onto the
trailer where it was taken to Columbus, OH
so it could make its big debut at the
Goodguys PPG Nationals.
With our new level of detail and its
documented performance, the GT55 made an
impression at the show. The car was given
one of the prestigious spots in the �top 5�
for Street Machine of the Year. With well
over 2000 hours into the car of late nights,
early mornings and seven days a week, it was
a great reward to be given this sort of
recognition.
Since its maiden voyage just over 7200 miles
of asphalt have passed under the GT55. The
suspension and steering deliver an unending
amount of confidence. The great thing about
the GT55 is that it is now like driving a
new car, the suspension and steering deliver
an unending amount of confidence no matter
how hard you push it. The car just begs to
be thrown into corners and around freeway
onramps. The interior of the GT55 has all
the features of any modern, high-end car;
sound deadening material, air conditioning,
a state of the art sound system and very
comfortable seating. In Grand Touring
fashion the car has been driven long
distances, including the 700-mile round trip
to the Goodguys Rod & Custom show in
Spokane, WA. With tunes cranked, it was
nothing to cruise along at 95mph while the
motor humming along at only 2300rpm. Another
trip took the GT55 with a group of other
cars down to the LA Roadsters show in June
of 2006. On the trip home we made covered
the 1138 miles from LA to Tacoma in just
over 16 hours! There are a lot more journeys
planned for the GT55 and hopefully they will
have a lot of twists and turns along the
way.
