Automotive Guide An Engineering Tour De Force

By: David Atkin
Automotive Guide

The 1970 Buick GS was one of the wildest of all Buicks on paper. Its 455 cubic inch mill was derived from the earlier 430 cid V8 and produced around 350 HP @ 4600 rpm. The torque output was a very strong 510 ft-lb @ 2800 rpm. It featured a 10:1 compression ratio and a Rochester 4-barrell carburetor; this engine could push the 3800 pound car down the ¼ mile in about 14.20 seconds @ 105 mph, and would perform a 0-60 run in 6.5 seconds.

Enter the Buick GS stage 1, which was an “engineering tour de force” according to Motor Trend magazine, the stage 1 upgrade would cost a very low $199.95, and for this price it was one of the best high performance engine packages you could get from any motor company, the stage 1 package included extra large nickel chrome stellite steel valves; big port cylinder heads with special machining and valve relieving; stronger valve springs; a high lift cam; a carburetor with richer jetting; blueprinted pistons notched for valve clearance, and an advanced performance distributor.

The stage 1 was available with either a special shift-governed automatic or a heavy duty four speed gearbox with a beefed up clutch, a stage 1 455 with the automatic transmission could do a 0-60 time of 5.5 seconds, and could zip down the ¼ mile in 13.39 seconds at 105.5 mph, Motor Trend clocked the stage 1 at 13.79 at 104.5 mph as it flew through the traps.

Buick had a horrible reputation of being a doctors car, or your grandma’s Sunday go to church car, but this was far from the truth, as you can see by the time that the car was capable of doing, and the all out performance of these cars.
