1970 Buick GS455 Stage 1 Muscle Car
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 Tri-City Plating. 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 iPod connection. 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?”
