Steve Stankus’ 72 Buick GS dips into the 11’s

Wednesday, May 8th, 2013

Steve Stankus is relatively new to the Buick performance world, having owned this beautiful 72 GS for only about 2.5 years. But he really hit a home run on his first effort. Steve purchased the Black GS from a GSCA Member in Ohio and started on his ideas for a street warrior.  The engine is a mild combination that works extremely well together. The shortblock houses a stock crank, and resized stock rods with ARP bolts. Wiseco Pro-True pistons and rings round out the rotating assembly. The compression ratio is 10.25 to 1. The cam is custom hydraulic  from Scott Brown at Competition Components, 226/239@ .050 with a shade over .510 lift when used with the1.6 ratio Comp Cams Ultra Pro Magnum Rockers. Machine work and assembly was done at Finishline Motorsports. Steve sent us the heads, for our full CNC porting treatment and blueprinted assembly. All of the standard Edelbrock Components were used. The Intake is an Edelbrock B4B, and both the heads and intake were painted Buick red to somewhat hide their origins. The Norm Dihle rebuilt Q-jet underneath a stock GS air cleaner rounds out the sleeper costume. The car currently has headers, but Steve plans on going to a set of ported stock exhaust manifolds. The Turbo 350 transmission was rebuilt by Joel’s on Joy, and uses a Kenne-Bell 10″ torque converter. The 10 bolt rear houses the original 3.42 gears. Mickey Thompson 275/60R15 Drag Radials try to get all that Buick torque to the ground. They have done a good job so far, with Steve recently laying down some passes in the 11.90’s at 112MPH on the first outing. Steve also wanted to thank good friend Rob Ross for lots of tech support. Great Job Steve, keep up the good work!!
