1973 Trans Am Exhaust SD455

1973 Super Duty Trans Am Exhaust, open hood scoop, Gardner Exhaust, SD455, idling Here is an excerpt from Popular Hot Rodding Magazine (September 1982) full page write-up about the 73-74 Super Duty Trans Am. The first and last paragraphs: "Probably one of the most awesome engines ever produced by Pontiac was the Super Duty which was built in two versions, 1961-1963 and 1973-1974. The Super Duty engine was ahead of its time churning out great doses of torque and horsepower. When combined with the Trans Am body style it made for an unbeatable combination of power and handling. ....... All Super Duty Trans Ams came with the 8 1/2-inch 10-bolt rear end, and with the optional 3.42 to 1 rear gearing were capable of running 13.90-second quarter mile times. If you're interested in picking up a Super Duty T/A today, they run between $5,000 and $10,000 depending on condition. If you can't afford one, pretend you can and take a test ride. Once you've been in one, you won't forget what they look, sound, and feel like."

133266 / 1973 Pontiac Firebird Trans Am Super Duty
For more information on this vehicle visit http://tinyurl.com/brpb3mq If you missed the opportunity to take home our RKM Performance restored SD-455 a few months ago, this badass Cameo Firebird is your second chance to become king of the muscle car hill! Assembled at GM's Norwood, Ohio manufacturing facility, and delivered to John Kralovetz via Bill Mowbray Motors in Brownsville, Texas, this awesome F2 Trans Am's factory correct appearance is simply spectacular. Thanks to spending most of its life in the warm and dry climate of the Southwestern United States, the car's rounded body was fairly straight when its restoration began; and given that body's distinct lack of rust, it should come as no surprise that panel gaps are excellent and fit feels rock solid. Of course, by the looks of this Pontiac's super smooth finish, someone must've spent weeks alone blocking and sanding every one of its panel in hopes of forming a laser-straight showpiece. And once the car's correct coat of Cameo White urethane was sealed in a glossy clearcoat shell, decorated with correct Trans Am call-outs and crowned with a coveted Screamin' Chicken hood decal, I'd say they definitely accomplished that goal. This car's highly detailed SD-455, which hangs a correct 490132 casting number and a November (K) 11th (11) of 1972 (2) casting date behind a correct XD engine stamp, has been bored .030 over, completely balanced and fully rebuilt to all its showroom glory. At the top of that big engine, a traditional Trans Am underhood induction system feeds fresh air to a correct 4-barrel carburetor that's bolted to a correct Pontiac intake. That intake sends a high octane air/fuel mixture into unique, high flow cylinder heads which have been equipped with Crane 1.65 roller rockers, high quality ARP rocker studs and traditional stamped steel valve covers. And those heads utilize a nodular iron crankshaft, Clevite main bearings, Clevite rod bearings, ARP Speedpro pistons and rings, and an NOS "Y" camshaft to create rocket-like combustion. Spark for that combustion is provided by a traditional points distributor which shoots fire through correct Packard TV R Suppression wires. Waste from that combustion is handled by fully restored Exhaust manifolds which roar into a stainless true dual Exhaust system. And heat from that combustion is controlled by a leak-free radiator which is hooked to fresh hoses via correct tower clamps and a correct plastic fan shroud. Behind that monster motor a virtually indestructible GM turbo-Hydramatic 400 transmission, which wears a 1973 (73) Super Duty-specific (P2Q) tag and a correct partial VIN, sends power to a familiar 10 bolt Safe-T-Track rear end that does a great job on both the back roads and the interstate. Below that stellar powertrain a rebuilt Trans Am suspension, which includes power steering, thicker sway bars, better shocks and stiffer springs, combines with standard issue power front disc and rear drum brakes to provide quick stops and great handling. At the center of the car, a power Boosting true dual Exhaust system utilizes an X-pipe crossover and welded Magnaflow mufflers to bark out a deep, vintage roar. And all this road ready hardware rolls on a restored set of Pontiac Rally II wheels which spin proven 235/60 BF Goodrich Radial T/As around pristine arrowhead center caps. In terms of interior décor, Pontiac's 70s team was firing on all eight cylinders. The rebuilt custom bucket seats are supple, firm, and look every bit as nice and rich as their name implies. Below those seats, like-new carpet, which is carefully protected by thick rubber mats, displays no fading or unraveling; and between those seats, a molded black console props an enclosed storage bin behind a chrome shifter and a factory correct 8-track player. At the sides of the car, hard to find door panels hang pristine chrome handles between chrome window cranks and full armrests. And in front of the driver, an optional tilt steering column spins a black Formula steering wheel around an engine turned instrument panel, sliders for the car's climate system and a correct Delco AM radio. If your definition of classic Detroit muscle is a highly accurate, beautifully presented, meticulously crafted Pontiac, it's your lucky day!
