When GM lifted their ban of engines larger than 400 cubic inches in
intermediate cars, the Buick camp responded with a legendary piece of
muscle car history. The GS was the go-to for anyone who put equal emphasis
on pure comfort and brute power. This Sloan-documented 1970 GS 455 is the
beneficiary of an extensive frame-off restoration which has already claimed
some significant awards. Accolades include a Concours Gold First Senior
award at the 2012 Buick Club of America Nationals.
While Buick's GSX made its presence loud and clear with two strong color
options, the GS455 went about things in a slightly more sophisticated way.
This GS 455 wears a refreshing mix of fresh Burgundy Mist and Glacier White
paint for a refined appearance. Only the functional hood scoops hint at the
cars performance capabilities. All brightwork has been polished or
replaced, including the showroom fresh bumpers which were rechromed by
Inside the car, Buick design remains at the forefront. An all new Pearl
White interior from Legendary Auto Interiors offers new carpet, bucket
seats, door panels, and a taut new headliner. Presentation is great thanks
to details like freshly rechromed center console trim and a new steering
wheel. Upgrades include a full Custom Autosound stereo system with direct
The stock Buick 455 was a strong engine, offering a factory rated 360 horsepower and 510
lb. /ft. of torque but this GS takes things to the next level. Lift the
hood and a deceptively stock-appearing bay hosts a fully rebuilt 470ci
Buick motor full of high-quality parts. Built by Tri-Shield Performance,
the block hosts pieces like Diamond forged pistons, Eagle H-beam rods, and
a TA cam. At the top, a ported stock intake works alongside ported and
polished aluminum SE Stage 1 heads to help make a stout 507 horsepower.
Behind that powerhouse, TH400 automatic transmission rebuilt by TSP spins
power back to a 12-bolt rear with versatile 3.31 gears. At either side,
headers connect to a 3-inch dual Exhaust system complete with an X-pipe and
Flowmaster 50 series mufflers. To the rear, a new Quantum fuel tank and
RobbMc fuel pump keep the big Buick properly fed.
During restoration, the frame was sand blasted and painted with an
industrial urethane before being joined by all new suspension components.
Power front disc brakes and rear drums provide plenty of stopping power
while a fully rebuilt power steering system ensures confidence through the
corners. The chassis meets the road through new Wheel Vintiques Buick Rally
wheels wrapped in Goodyear Polylgas tires.
Offering a near-perfect blend of show and go, this award-winning 1970 GS
455 is a great reminder of Buick's performance heritage and a resounding
"Yes" to the old slogan, "Wouldn't you really rather have a Buick?"

1972 Buick GS Stage 1 does the quarter mile at Muslepalooza and Wins!!!
My dads all original (minus one repaint), # matching 1972 Buick GS Stage 1
auto does the quarter mile at Musclepalooza @ Lebanon Vally Raceway. The
drivetrain has never been touched and has 110,000 miles on it. This wasn't
the fastest run as his first run (and first time ever with this car) ran a
14.43 if he had traction off the line the times would probably be closer
to 14 flat. He ran a 14.61 @ 94mph and wins!!!
