If you saw Brian Sobczykz’s Blue 72 Buick GS at Norwalk this past weekend, you probably thought it was a nice looking 12 second car. It can’t be much faster than that can it? Look at that. It has a stock radiator. Clutch fan and stock water pump. All those stock parts add up in weight. The 72 weighs in around 3900 lbs. The interior doesn’t give away the car’s performance either. Stock bucket seats and full interior. Is that a tilt steering column? Nice car, shame it’s not faster. But it is faster. A lot faster. Brian ran a string of passes between 10.62-10.65 all over 124 MPH. Wow, cool! Rumor on the street is it’s a stroker motor with a roller cam. But it’s not. The engine is 464 CID (4.350 bore x 3.90 stroke.) Stock cast crank. Stock rods with ARP bolts. Custom Ross Dished pistons. The heads are ported TA stage 1 units. The TA Single plane intake with a Dominator is one of the few things that give away the car’s potential. It doesn’t even sound radical. The custom 256 at .050 solid flat tappet has a little lope to it, but the X pipe and large case 3″ mufflers tone it down enough that the police barely give it a second look on the way to the local cruise night. The tailpipes running to the bumper complete the sleeper look. A race converter from PTC custom matched to the cam and the rest of the combination, and transfers power through the TH400 Converter and 4.10 gears.
Update: All good things must come to an end. After 7 years of fun and abuse, Brian’s engine expired at Milan last night, 9/3/2009. Watch for a new combo appearing soon!
