The Pontiac 389 engine is one of the most iconic and recognizable American V8 engines of all time. This engine has powered some of the most iconic vehicles in American automotive history, including the legendary Pontiac GTO. With its large displacement, powerful performance, and iconic styling, the Pontiac 389 engine has remained a popular choice for hot rodders and classic car enthusiasts for decades. But how much does this classic engine weigh? Depending on the configuration and components, the Pontiac 389 engine can weigh anywhere from 500 to 600 pounds.
It’s possible that the shipping company is trying to inflate the engine’s weight in order to get a higher package weight. A complete engine of a 500-600 pound Pontiac 400 is usually the heaviest. I would put it in the 700 to 800 range. They are also weighing a fork truck with a pallet. This Trans Am Ws6, W72 400, holley 650, #62 heads (toy), and silverado 1500 daily driver from 1979 was manufactured by HOLF. Find some documents/facts (Google) that confirm the weight or meet the motor at the dock and make them prove it. It would have been easy for it to get caught in the storm that hit two weeks ago.
The Pontiac 389 Super Duty is rated at 368 horsepower in the Super Duty trim.
Despite their docile nature, they were responsive and flexible, capable of moving a 3,600-pound Goat around with authority while also being docile enough for a trip to the grocery store. The 389 engine shined brightly in the relatively light body of the GTO, making it an ideal vehicle for street performance enthusiasts.
Is A Pontiac 389 A Big Block Or Small Block?
A Pontiac 389 is considered a big block engine. It is a V8 engine with a displacement of 389 cubic inches and is considered to be one of the most iconic Pontiac engines of the 1960s. The Pontiac 389 was the engine of choice for the GTO in the mid-1960s and was known for its power and performance. It was available in a variety of configurations including single and dual four-barrel carburetors, and was also available with a Tri-Power setup. It was also used in other Pontiac models such as the Bonneville and Grand Prix. The Pontiac 389 was a reliable and powerful engine, and is still a popular choice for classic car enthusiasts today.
There was no other animal that could compete with the Pontiac 455 in terms of power. Its forged steel crank, forged steel rods, and high compression set it apart from the other two engines, making it the only one capable of punishing high-performance lifestyles. The Ram Air IV engine, on the other hand, was the only one with a horsepower rating of 366 and a torque rating of 500 feet per pound. The Pontiac 455, as a result, was crowned the best performing vehicle in the GM world. The Pontiac 455 is a vehicle from the golden age of muscle cars, a testament to GM’s engineering prowess. The engine was the most powerful and advanced of the three big block V8 engines offered by the company. The Ram Air IV option allowed it to really strut its stuff because it was a power plant capable of taking almost anything thrown at it. In terms of power and performance, the Pontiac 455 was the vehicle of choice for those looking for a dependable engine in 1970. In addition to being the only engine designed specifically for the demands of a high-performance lifestyle, the Ram Air IV option gave it an advantage over the competition. It was without a doubt one of the most powerful muscle cars of the era.
What Was Pontiacs Biggest Engine?
I’m not exaggerating when I say the car is a 601-inch long. This specific engine has never been at this high level until recently. In the 1970s, production Pontiacs had 455 cubes of cooling, which was sufficient in the day, but aftermarket engines of 500-square-inches and larger are now relatively routine.
In the early 1900s, the Oakland Motor Car Company was established in Pontiac, Michigan. Within a few years, Oakland was a division of General Motors. Oakland introduced the Pontiac model line as a companion model in 1926. The 287 block, which was built by Pontiac, was built with five main journals with a diameter of 2.5 inches and a diameter of 2.5 inches. The V-8 engine in Pontiac was made up of a machined (decked) cylinder head and rocker arm pivoted on a single stud. coolant to the cylinder heads before the engine’s lower end was directed through a reverse-flow cooling system. In mid-1955, Pontiac introduced the first extra-horsepower package.
Tri-Power was introduced in 1957 as a way to appeal to young hot rod enthusiasts. In its original form, the Super Duty engine was a 4-barrel, 4-bolt, 10.5:1 compression, and 1.65:1 ratio rocker arm. The Super Duty package also included a forged-steel crankshaft and connecting rods, a solid-lifter camshaft, and high-flow cylinder heads and exhaust manifolds. In 1960, the Pontiac Super Duty 389, with a power rating of 348 horsepower, and the Tri-Power 389, with a power rating of 363 horsepower, were the only cars rated at 348 horsepower or higher. The 421 version of the Super Duty package was released by Pontiac at the end of the 1961 model year. It was rated at 405 horsepower and used two 4-barreled guns, making it one of the most efficient firearms on the market. It and the Super Duty 389 became factory options in 1962 to comply with racing regulations.
The cylinder head for the Pontiac Super Duty engines was updated in 1963. The SD-389 had a power rating of 395 horsepower, while the SD-421 had a power rating of 405 horsepower. General Motors ended its factory-backed racing program in the United States, and the Pontiac brand began street performance. The first vehicle to use the concept of combining a large cube engine with a small body was the GTO, which was produced in 1964. The 421 H.O. V-8 engine was introduced for the first time in 1964, making it a powerful performer. The engine was essentially a detuned SD-421 engine with number-716 cylinder heads, cast-iron exhaust manifolds, and a high flow intake system. To meet General Motors’ power-to-weight ratio standards, engine sizes were limited to 389 liters.
General Motors was the first to ban multiple carburetions on all vehicle models in 1967. For 1967, the full-size engines in the Pontiac line required even more power. To improve flow, an exhaust manifolds were streamlined, and the bore diameter of the exhaust manifolds was increased. Since the 1960s, General Motors has prohibited the use of multiple carburetion. As a result of the rapid development process, Pontiac was able to produce a powerful V-8 in the Ram Air II (R/A II). The Ram Air II and Ram Air IV engines were the most popular engines produced by the company between 1969 and 1970. The second-generation Firebird Trans Am quickly established itself as one of the world’s premier performance models.
Collectors are in high demand for such items today. It was necessary to increase the displacement in order to motivate GM’s full-size cars. During the 1971-1974 model year, Ram Air IV and R/A IV engines were used in the V-8 engines. For 1971, General Motors imposed an industry compression ratio limit of 8.5 to one. The power of the 1972-1974 Pontiac Super Duty 455 was increased to 6,000 rpm. These engines were only used for two years, when fewer than 1,300 were built. It was designed to run at a maximum speed of 6,000 rpm and achieves this by utilizing the SD-455 engine.
The turbocharger was installed in the 301 for the 1980 model year as a result of its increased performance. There were only 295 SD-powered Firebirds built in 1973, and each had 290 horsepower. Block castings made of lighter materials were used in the 350 and 400 engines of the Pontiac brand. The 455 was phased out after 1976, and the 415 became the new performance model. For 1978-1982, a 400 block casting was introduced for T/A 6.7 engines that featured a nameplate of 400 block cylinders. By 1979, only the 301 V-8 was manufactured by the company. The last production of the Pontiac V-8 occurred in March 1981.
In total, there were 14624,886 engines produced. During the nineteenth century, the Pontiac brand’s performance image remained constant. Arnie Beswick, Truman Fields, Jim Hand, John Angeles, and Pete McCarthy were all successful candidates for the Pontiacs during the 1950s, 1960s, and 1970s. There are twin turbochargers in Rodney Butler’s 482-ci Pontiac V-8 that provide 40 pounds of boost. A quarter-mile run can be completed in as little as 7.20 seconds, with a top speed of 190 miles per hour. As a premier engine builder, we are proud to have produced a number of premier Pontiac engines for Butler Performance.

What Pontiac Had The Most Horsepower?
This is an overview of the 2006 Pontiac GTL, which is the fastest car ever built. The 2006 Pontiac Gt is the fifth-generation model of the popular vehicle. This car comes equipped only with one engine option: a monster 6.0-liter naturally aspirated LS2 V8 engine capable of 400 horsepower and 400 pound-feet of torque at speeds ranging from 5 to 200 mph.
Engine Weight
Eight-cylinder engines typically weigh between 400 and 450 pounds. There are also 700 pounds to be weighed. The combustion systems in more expensive luxury vehicles and sports cars are similar to those in high-performance vehicles. In addition, ten and twelve-cylinder engines weigh more than 800 pounds.
Does the weight of your engine have anything to do with performance? This article will walk you through the process. Diesel engines are heavier than gasoline engines. This type of combustion system is used in high-performance luxury vehicles and sports cars. The engines of the 10- and 12-cylinder models are enormous. The weight of an engine is determined by a variety of factors, the most important of which are its size/displacement, model release year, and construction material. The goal of automobile manufacturers is to improve power by utilizing smaller engines.
Engines manufactured in the recent past are more technologically advanced than those manufactured in the past. Your vehicle’s brand, maintenance culture, and driving habits all affect the life of your engine. Lighter vehicles are typically more capable of handling and consuming less fuel. When it comes to engine weight, we do not have any evidence that bigger is better. The long term goal of automobile manufacturers is to develop more compact combustion systems that are both efficient and powerful at the same time.
In 1967, Chevrolet’s 427 engine improved significantly thanks to the L-88 option. The L-88 was built with an aluminum cylinder head, larger crankshafts, and larger carburetor, allowing the 427 engine to reduce its weight from 687 pounds to almost the same as the 327 engine, at 575 pounds. As a result, Chevrolet’s L-88 engine was more powerful and efficient, allowing it to improve engine performance significantly. By providing a lightweight, powerful engine, the L-88 was a significant advance in engine technology. To compete with other engines on the market, including the Olds 350-422 V8 at 725 pounds, the Olds 371 and 395 at 760 pounds, and others, Chevrolet developed an engine specifically for the market. The L-88 was a significant milestone in the development of engine performance, and Chevrolet should be proud of its achievement.
