1983 Pontiac Firebird History



The 1983 Pontiac Firebird remained basically unchanged from the previous years 1982 Pontiac Firebird. All '83 Firebird models were switched to a T-handle automatic gearshift knob. Shift indicator changes for the Automatic Overdrive 700-R4. Midyear the L69 high output 305 was introduced. The carbed 190hp V8 was virtually identical to the L69 in the Z28 but used a different aircleaner assembly. Instead of the Camaro's dual snorkle aircleaner, the L69 Trans Am received yet another functional cold air intake designed to utilize the bulged hood. The Trans Am was selected as the DAYTONA 500 pace car. Pontiac sold 500 Daytona pace car replicas thru their dealerships. The limited edition cars featured full body ground effect skirts extending around the entire car. The front bumper grills were replaced with molded plastic panels, with the "Trans Am" script on the right panel. Also included were Recaro leather seats, special 15" "AERO" wheels with smooth covers, red gauge backlighting, leather appointments, Daytona 500 graphics, and a unique white and charcoal paint scheme. The pace cars were only available with the LU5 Crossfire injected 305 or the L69 carburated 305. Other special packages were also available such as the Recaro trim package which included the Recaro seats, and black paint with gold highlights.
