Most car fans know that bigger engines are more capable of producing higher power. They have bigger bores, strokes, and high flow intakes that can feed the engine with more fuel and air. However, modern times have brought the auto world downsizing. These fuel-efficient engines can match a larger V8’s power with the help of turbocharging and modern technology. Yet displacement is still king. If you want a lot of power, the best way to do so is with a lot of cylinders and significant displacement.<\/p>\n

However, in the car industry, some huge engines were downright disappointing. They were massive, but somehow pathetic in their power output; even bordering on disgraceful. Today, we’ll discuss those rare kinds of engines that were massive machines with ridiculously low power. Most of them were the victims of tightening emission regulations and low compression approaches. But some of them were simply products of poor engineering. Either way, these engines taught today’s car world a thing or two about not what to do wrong. Check these engines out right here.<\/p>\n

Cadillac 500 CID<\/h2>\n

The Cadillac 500 CID is a typical example of a massive engine with enormous potential ruined by environmental standards. This mighty power plant was introduced in 1970 in the Eldorado and remained the top engine choice for almost a decade. In 1970, this engine produced a healthy 400 HP and 550 lb.-ft of torque, which made it one of the most powerful engines ever put in a production vehicle. Unfortunately, this lasted only for a year before it began to decline (via Driving Line<\/a>).<\/p>\n

\"\"<\/p>\n

By the second half of the 1970s, Cadillac’s mighty 500 V8 lost all of its power. The engine was installed in other models like Fleetwood. As time progressed and US manufacturers introduced low-compression engines, this mighty unit delivered only 190 to 210 HP and almost 200 lb.-ft of torque less than the 1970 model. Of course, its performance was pathetic as well.<\/p>\n

Ford 460<\/h2>\n

The legendary 460 V8 was one of the long-lasting Ford engines that debuted in 1968 and sold well into the ’80s. It started as the top-of-the-line engine for Lincoln but later was an option on Mercury and Ford models. In the late ’60s, this powerful Ford unit delivered 365 HP and provided the Lincoln Mark III with convincing performance for a luxury car (via Moto Verso<\/a>).<\/p>\n

However, it had to avoid the destiny of all other US-made engines in the ’70s and couldn’t do so. It lost its power with smaller intake, low-compression heads, catalytic converters, and so on. By the late ’70s, the 460 had only 197 HP. After that, it was offered as an option on Ford Econoline vans. Ford never admitted it, but it wasn’t as powerful as it needed to be to put in a passenger car.<\/p>\n

Pontiac 301 Turbo<\/h2>\n

When somebody says “V8 turbo,” you know they are talking about an immensely powerful motor. Eight cylinders with the help of forced induction is a sure recipe for big power and performance. That is if we’re talking about modern engines. In 1979, this wasn’t the case. The days of big cube motors and high horsepower ratings<\/a> were gone, so Pontiac decided to invest in new technology to generate power. That new technology was turbocharging. So in late 1979, Pontiac introduced the Trans Am Turbo (via Pontiac V8<\/a>).<\/p>\n

The engine in question was the 301 V8 with a Garrett turbocharger bolted onto it. The power output was modest at 200 to 210 HP, but the torque number was high at 340 lb.-ft. This resulted in a hint of performance that was still far from anything substantial.<\/p>\n

Ford Windsor 302<\/h2>\n

Ford introduced the Windsor family of V8 engines in the early ’60s. Very soon, it became the “go-to” engine on Mustangs and Shelbys. With its lightweight casting, the 260 and later 289 V8 were very successful on the street and the track. However, in 1968, Ford introduced the 302 aimed at the middle-of-the-road V8 used in numerous vehicles (via Vehicle History<\/a>).<\/p>\n

In 1975, the Mustang II gained the V8 option in the form of a 302 engine. Mustang fans were very enthusiastic about this but were also very disappointed soon after the spec sheet was released. The low-compression V8 had just 140 HP on tap, which is nothing in terms of performance and character. The result was seen as disgraceful for a once-powerful unit that won races. Just compare that to the modern-day Mustang’s 5.0-liter engine. The 2023 5.0 Coyote has over three times as much power.<\/p>\n

Chevrolet L83<\/h2>\n

The Chevrolet small-block V8 family of engines has been around since 1955. It is still a relevant powerplant used in numerous GM models. Of course, during the 1970s and ’80s, it was affected by tightening emissions regulations. The 5.7-liter produced terrible figures and not-so-convincing performance (via Old Car Memories<\/a>).<\/p>\n

In 1984, Chevrolet was proud to show a brand new advanced Corvette C4. It was all-new apart from the engine, which was an anemic 5.7-liter V8 strangled by emissions regulations and delivering just 200 HP. Yes, it was amongst the fastest sports cars on the road in the mid-’80s, but its power is ridiculous nowadays.<\/p>\n

Bentley 8-Litre<\/h2>\n

The pre-war car industry was full of massive engines with relatively low power figures. Development limitations were the reason. But sometimes manufacturers deliberately made massive units with low power so they could have smooth driving dynamics thanks to enormous torque. One such example is Bentley’s 8-Litre unit (via Car and Driver<\/a>).<\/p>\n

With almost 500 cubic inches of displacement, this was only a six-cylinder unit with pistons diameter of sewage drains. The power output was 220 HP, an astonishing number for its day but diminutive today. Interestingly, such a massive engine was bound to be heavy, but Bentley used modern<\/a> and lightweight materials to keep it reasonably light. Only 100 cars left the factory in late ’30.<\/p>\n

Rolls Royce 6 ¾ -Liter V8<\/h2>\n

For the better part of the late 20th century<\/a>, Rolls Royce models were powered by an in-house V8 engine designed to be smooth, quiet, and refined. In those days, Rolls Royce was notorious for deliberately not stating the engine’s power and torque figures and instead only mentioning that the power was “adequate.” In a world of spec sheets and customers wanting to know every detail, calling something “adequate” is not enough (via Which Car<\/a>).<\/p>\n

\"\"

That was because Rolls knew that their “six and three-quarters” V8 wasn’t exactly a powerhouse. With outdated construction, low compression, and conservative intake, this big V8 produced only about 215 to 240 HP depending on the model year. However, it was enough for cruising in style.<\/p>\n

Chevrolet LG4 V8<\/h2>\n

Chevrolet’s small-block V8 in Camaro or Corvette was always a recipe for a fun muscle car with enough power to keep you smiling for days. However, you may have an early ’80s C3 ‘Vette or F-Series Camaro. In that period, Chevrolet produced the 305 cid V8 with 180 HP, which had automatic transmission (via Corv Sport<\/a>).<\/p>\n

Of course, those models didn’t perform very well, and GM was criticized for producing low-performance engines and putting them into cars that symbolized performance.<\/p>\n

GM Diesel V8<\/h2>\n

Oldsmobile was at the forefront of this new trend<\/a> with the introduction of the diesel engine in passenger cars. In those days, American buyers were largely unaware that you could use diesel fuel for your vehicle. European customers already had a couple of diesel cars on the market, but in the US this was new. Oldsmobile introduced the 4.3-liter V8 diesel engine as an option for the Cutlass line. And very soon, this model was subject to an enormous amount of recalls and engine swaps. Simply, the 4.3-liter tended to explode and shatter during everyday driving. It had only about 85 HP (via Diesel World Mag<\/a>).<\/p>\n

Passengers didn’t get hurt, but the car was unusable and suitable only for scrap. Oldsmobile later introduced a bigger 5.7-liter diesel. Which was somewhat better but the 4.3-liter is considered the worst diesel engine in history<\/a>. The 5.7-liter was also very underpowered with only 122 HP on tap.<\/p>\n

AMC 4.2-Liter<\/h2>\n

The venerable AMC six-cylinder was in production for an unbelievable 50 years and has outlived its parent company. It started as an economic engine with smaller displacement and decent power and managed to be the best engine option in numerous AMC and Jeep models (via Jeep Tech<\/a>).<\/p>\n

The 4.2-liter had outdated construction, but it was an insanely dependable motor. Overall, it required low maintenance and could run on low-octane fuel. During the ’70s, it was common on AMC models. But with low compression, it had only about 120 HP, which was a ridiculously underpowered figure.<\/p>\n\n","protected":false},"excerpt":{"rendered":"
