1973 Pontiac Firebird Trans Am Hardtop (more photos 👇)
1973 was the only year a Trans Am buyer could specify Brewster Green (Code 48), which happened to coincide with the debut of the large phoenix hood graphic as an option. Priced at $55.00 and officially called the hood bird decal, it became known almost universally as the “Screaming Chicken.”
The second-generation Firebird arrived in February 1970 on a redesigned F-body platform shared with the Chevrolet Camaro, bringing more aggressive sheetmetal and accommodation for Pontiac’s largest engines.
Trans Am-specific hardware included a front air dam, fender flares, functional front fender air extractors, and a rear-facing shaker scoop mounted through the hood.
By 1973, the standard Trans Am engine was the L75 455ci V8, rated at 250 net horsepower and 370 lb-ft of torque. The optional Super Duty 455 (SD-455) variant (hand-assembled, with round-port cylinder heads and forged internals) was rated at 290 net horsepower and 395 lb-ft of torque.
Total 1973 Trans Am production came to 4,802 units. Of the 142 built in Brewster Green, 72 were equipped with automatic transmission.
