This 1979 Pontiac Trans Am was originally equipped with a 403 cubic inch Oldsmobile V8, and although it was pretty hot for the time, it just isn’t enough for the owner today. The car came to the V8 Speed & Resto Shop for some high-performace upgrades including a GM LS3 485 HP V8 engine fed by a Holley EFI system, and it will handle better thanks to a Ridetech Street Grip suspension system with YearOne wheels. Wilwood brakes will haul it down in short order. Before all the fun, we had to fix some rusty floors, which was a good time to fabricate a custom firewall for the car as well. Follow along with all the progress here!
