AWD 1971 Firebird with a supercharged LSx V8

Gregg Hamilton loves being Ken Block’s lead mechanic and Pontiac Firebirds. You might remember his previous project, a Trans-Am with a twin-turbo LSx V8. Three years ago Gregg started building a second Firebird he could drive without fear of damaging the finish. He started with a 1971 Firebird Formula that previously sat for a decade in Las Vegas. Under the body he installed modified Corvette C6 subframes, custom pushrod suspension with QA1 coilovers, and C6 Z06 Corvette calipers with Wilwood rotors (6-piston front, 4-piston back). Next came a supercharged LSx V8 estimated to make 600+ hp thanks to a 5.3 L block with aftermarket crank, rods, heads, and a Weiand blower. The engine is mated to a Nissan R32 five-speed manual transmission, R33 transfer case, Q45 diff in front, and 300ZX diff in back.

  1. That is one bad ass bird. I love the look of excitement and happy he is with his creation. Beaming and rightfully so. Only two years and with his workload the man doesn’t mess around. I hope he smiles as big as he does in this video every time he gets behind the wheel and fires this beast up. This body style of Firebird has been my favorite ever since I saw one and I cannot get enough of this AWD Daily Driver.
