In 1980 Pontiac answered the death of the big-block by bolting a turbocharger to a 4.9-liter V8, badging it as the Indianapolis 500 Pace Car, and daring buyers to take it seriously. Only 5,700 Special Edition Turbo Trans Ams were built, every one with T-tops, Cameo White paint and a boost gauge sitting on the hood. Read on to find out why a car once dismissed as a malaise-era compromise is quietly climbing in value.
Pontiac rated the 1973 Super Duty 455 at 290 net horsepower, a figure most experts believe was deliberately conservative by around 85 horsepower. The engine used a reinforced block, four-bolt mains, forged rods and pistons, and a nitrided crankshaft. Only 252 SD-455 Trans Ams were built that year out of 4,802 total, split 72 manual and 180 automatic. Read on to find out how one engineering team built a genuine muscle car in the year everyone else quit.
In 1981, Pontiac answered a shrinking performance budget with a genuinely strange idea: the first mass-production turbocharged V8 in an American car, wrapped in the loudest graphics package the Trans Am ever wore. The 210-horsepower engine was groundbreaking and unreliable in roughly equal measure, and reviewers are still divided on whether the gamble paid off. Read on to find out why collectors now pay a premium for the rare survivors that got it right.
This 1979 Pontiac Trans Am, photographed courtesy of Gateway Classic Cars, runs a 403-cubic-inch V8 backed by a Turbo 350 automatic. The catch is that Pontiac did not build the engine, Oldsmobile did, and no manual transmission was ever offered behind it. Yet 1979 turned into the single best sales year the Firebird nameplate ever had, with more than 211,000 built. Read on to find out how a car with a borrowed engine outsold every version that came before it.
Pontiac hasn’t built a car in years, but a Tallahassee shop called Trans Am Depot will still sell you one — by starting with a fifth-generation Camaro and spending eight weeks turning it into a Hurst Edition Trans Am tribute, gold logo, shaker hood, and all. Between the base conversion, a fully optioned Camaro donor, and a supercharger kit, the final bill can climb past $100,000. Read on to find out what that money actually buys, right down to the carbon fiber sill plates.
