One of our completed projects is a 1970 Buick GS Stage 1 that will be built for the street as well as the strip.
Motor Trend Magazine tested these cars back in 1970 and back then they ran a 13.38 @ 105 MPH. That quarter mile time placed the 1970 Stage 1 GS as one of the quickest American Production cars ever built. A couple guys have actually built these cars to run 10 Second quarter mile times in “Stock Appearing” trim. Stock Appearing simply means the car will look like it did the day it rolled off the showroom floor. This car will be built using those
same guidelines. No after markets parts will be visible in the engine bay or the interior. Ours will even be running the Factory Quadrajet Carburetor and Cast Iron Exhaust Manifolds!
Update:
Best E.T. so far with a Factory Stock-Low Compression Motor:
12.72 @ 102 MPH 1.73 60 Foot Time
Non Stage 1, No Port work, 8.5 to 1 Compression, Small Cam
I feel the car would easily run 11’s with a 1970 Spec Stage 1 Motor and Port work.
Update #2:
This car has been sold to a good friend and has now received an all Aluminum Stage 2 Motor with Fuel Injection.
The assembly process has begun. I really didn’t want any “Race” parts to be visible on this car so
the Battery Disconnect Switch was placed on a hinge so we can hide it when
not at the Track. Second photo shows the switch in the “hidden” position.Shown here with our “Sleeper” wheels Fuel Tank Rear View – Right Side (Note Factory Shocks!) 2.5″ Exhaust System w/ Dyno Max Mufflers Cro Moly Driveshaft Loop Stock Lower Control Arms Underside Engine Bay Engine Bay Engine Bay Engine Bay – Driver Side View Engine Bay – Passenger Side View Clutch Fan Assembl Our Carburetor was sent to QuadrajetPower.com It looks and performs better than new!

Car has been sold and is now sporting a Full Blown Stage 2 Motor and Fuel Injection.Update – October 2016
Current Car owner had us install a Full Blown “572” Stage 2 Motor
This motor made over 700 H.P. and 700 + Torque
We also installed Air Conditioning and Pro Touring Suspension from Speed TechA Stage 2 hood Scoop was also added for proper hood clearance The Current owner wanted his now toy to match his 1972 Stage 1 so we swapped out the
Front & Rear Bumpers, Headlight Bezels, Hood Trim and Grill.
