This 1979 Pontiac Firebird Trans Am came from the factory with an 403 ci Oldsmobile V8 making 185 horsepower. The owner sent it to V8 Speed & Resto Shop in Red Bud, Illinois for some performance upgrades. While there they replaced the factory engine and transmission with a LS3 V8 making 480 horsepower and 4L70E four-speed automatic transmission. The car also received new floors, custom firewall, Vintage Air system, Ridetech Street Grip suspension, Wilwood brakes, and YearOne Snowflake 17-inch wheels.
