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

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 lineÂ’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 PontiacÂ’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.

Junkyard Gem: 1984 Pontiac Fiero with supercharged 3800 V6 swap

Like the Corvair, the Vega, and the Citation, the Pontiac Fiero was a very innovative machine that ended up causing General Motors more headaches than happiness, and Fiero aficionados and naysayers continue to beat each other with tire irons (figuratively speaking, I hope) to this day. The General has often proved willing to take the occasional big gamble and huge GM successes in engineering prowess (including the first overhead-valve V8 engine for the masses and the first real-world-usable true automatic transmission) and marketing brilliance (e.g., the Pontiac GTO and related John DeLorean home runs) meant that the idea of a mid-engined sporty economy car (or economical sports car) got a shot from the suits on the 14th floor. Sadly, the Fiero ended up being the marketplace victim of too many issues to get into here, and The General pulled the plug immediately after the 1988-model-year suspension redesign that made the Fiero the sports car it should have been all along. But what if the plastic Pontiac had never suffered from the misery of the gnashy, pokey Iron Duke engine and had been built from the start with a screaming supercharged V6 making way better than 200 horsepower? The final owner of today's Junkyard Gem sought to make that very Fiero, by dropping in one of the many supercharged 3.8-liter V6s installed in 1990s and 2000s GM factory hot rods. The first Fieros came out in 1983 for model year 1984, and the only engine available that year was the Iron Duke 2.5-liter four-cylinder, which generated its 92 horsepower with the full-throated song of a Soviet tractor stuck in the freezing mud of a Polish sugar-beet field. The 2M4 badging stood for "two seats, mid-engine, four cylinders," just as the numbers in the Oldsmobile 4-4-2 once represented "four carburetor barrels, four-speed manual transmission, dual exhaust." This car is a top-trim-level SE model, which listed for $9,599 (about $24,200 today). The no-frills Fiero cost just $7,999 that year, making these cars far cheaper than the only other reasonably affordable new mid-engined car Americans could buy at that time: the $13,990 Bertone (aka Fiat) X1/9. The Toyota MR2 appeared in North America as a 1985 model with a base price of $10,999 and promptly siphoned off the car-buying cash from a bunch of potential Fiero shoppers.

Pontiac Firebird in latest Generation Gap scrap

Generation Gap is mining the Lingenfelter collection again this week to compare two very different interpretations of the Pontiac Firebird. An original 1968 example goes toe-to-toe with a 2010 Lingenfelter Trans Am to see whether the old man or the modern re-imagining takes the crown.
Being from the Lingenfelter collection, both cars are absolutely immaculate. The '68 packs a Pontiac 350-cubic-inch (5.7-liter) V8 with a claimed 320 horsepower and some classic, muscular style with a hood-mounted tach. Plus, it's painted in an understated shade of green that you don't usually see.
In the other corner is Lingenfelter's pumped-up take on the classic shape based on the modern Camaro, and this is just one of six concept versions ever made. It wears an eye-catching, vintage-inspired livery of blue with a white stripe package. Under its shaker hood is a 455-cubic-inch (7.5-liter) V8 with a reported 655 hp and 610 pound-feet of torque.
