Classic Pontiac Trans Am Firebird Super Duty 455 sells for nearly $90,000

Jun 20, 2023

Historically, the Pontiac Firebird Trans Am raised the performance levels a notch or two over a plain Firebird in the muscle car hierarchy of the Sixties.

But the Super Duty 455 version of the Trans Am — that number represents the cubic inches of the hand-assembled V8 engine — moved the performance needle big time in 1974.

So much so that a clean example of the machine sold recently on the Hagerty Marketplace auction site for $89,296.

Advertised with just under 54,000 miles on the clock and having undergone a thorough restoration, the Buccaneer Red model was one of just 943 Pontiac Firebirds equipped with the Super Duty 455 package for the 1974 model year. That build had also been offered in 1973.

The Hagerty listing drew more than 21,000 views and 39 bids. According to Hagerty's valuation report, a similar car would be worth $85,700 in good condition, and $103,000 if it was in ‘“concours condition.”

The Super Duty motor borrowed technology from the line’s 366-cubic-inch NASCAR engine, and featured heavy-duty connecting rods and an entirely new block with a revised crankshaft and heads to deliver a claimed 310 horsepower.

The Firebird that sold was indeed loaded, with a three-speed Hydra-matic transmission (which surely reduced its overall value), power locks and windows, AC, dual exhausts, heavy duty stabilizer bars all around, and a “custom Interior trimmed in Red perforated Morrokide vinyl upholstery.”

The entry of Pontiac’s pony car in the U.S., facing off against the Mustang and Camaro, dates back to 1967, when it was offered with an inline six and optional V8. The first Trans Ams were introduced two years later, the name derived from a handling package. General Motors ceased production of new Pontiacs in 2002 owing to declining sales and losing stakes in the sports coupe market. The big 455-cid V-8 had disappeared years earlier.
