GM’s Small Block V8 Turns 70, Isn’t Going Anywhere

  • One of the most famous engines in the world is celebrating a major milestone as Chevrolet’s small block V8 is turning 70.
  • The engine was launched in a handful of 1955 models including the Corvette and Task Force pickup.
  • GM has already confirmed plans for a sixth-generation small block V8 and it promises to combine power with efficiency.

The death of the V8 engine has been often talked about, but it’s alive and well at Chevrolet. That’s certainly clear as the company recently introduced the Corvette ZR1, which features a twin-turbo 5.5-liter V8 with 1,064 hp (793 kW / 1,079 PS) and 828 lb-ft (1,121 Nm) of torque.

While that’s the latest and greatest, their small block V8 is celebrating a monumental milestone. The engine debuted 70 years ago in 1954 with a displacement of 4.3-liters.

A long lasting legacy was almost destined from the beginning as the engine was installed in the 1955 Corvette, where it produced 195 hp (145 kW / 198 PS). This was a huge boon for performance fans as it offered nearly 25% more horsepower than the 3.9-liter inline-six.

The engine was also offered as part of the 1955 Task Force lineup, which included the Cameo Carrier that was billed as the “gentleman’s pickup.” Needless to say, this association continues to this day as small block V8s are prominently featured across the Silverado lineup.

GM’s Small Block V8 Turns 70, Isn’t Going Anywhere

While charting the changes would take an eternity, as there have been five generations and countless improvements, the latest lineup includes 5.3-, 6.2-, and 6.6-liter V8s. They can be found in everything from pickups to performance cars including the Corvette and Cadillac CT5-V Blackwing.

While rivals such as Stellantis have largely said goodbye to the V8, General Motors has already announced plans for a sixth-generation small-block engine that will be built at plants in Michigan, Ohio, and New York as part of an $854 million investment. The automaker has been tight-lipped about details, but promised the mill will showcase “power and efficiency.”

Gearhead Nirvana: We Visit Porsche’s Atlanta Workshop Where Classics Get Reborn

Maintaining any car is a duty that different owners approach in vastly different ways. For some, a few zip ties and a rattle can of spray paint is good enough. Far on the other end of the spectrum are owners like the ones who take their car to the Porsche Classic Center in Atlanta. During our trip there to see the new Macan EV in virtual reality , we had the opportunity to tour the Classic Center as it was deep in the midst of multiple repair and restoration projects.  To the owners of these cars and to the Porsche brand itself, what these mechanics, technicians, upholsterers, and painters are preserving is heritage. The center’s mantra “As good as new. But with even more character” is on display for anyone who visits the site.

The New Honda Prelude Will Be A Global Model, But It Won’t Be A Toyota GR 86

Image
Last month, Honda rolled out the red carpet for the the hybrid Prelude Concept , heralding the comeback of a historic name in the motoring world. Now, this car has been given the green light as a global model, set to cater to both right- and left-hand drive markets. However, it might not quite rev up to be the full-throttle sports car many enthusiasts were anticipating Despite being labeled a concept by Honda, the car presented at the Japan Mobility Show (JMS) looked quite production-ready. And if we know anything about Honda, they have a knack for unveiling thinly-disguised production cars as concepts. Take the last two Civics, for example. The 10th-gen Civic Concept was more or less the Civic coupe of that generation with a more aggressive stance and altered bumpers, while the 11th-gen Civic Prototype was virtually the same sedan that made it to production.

As Good As New Porsche 918 Spyder With Just 43 Miles Could Fetch $2 Million

Image
This Porsche 918 has been kept in a climate-controlled storage facility ever since it was delivered. The car is one of just four Hong Kong-spec 918s in existence. Driving the hypercar is a 4.6-liter V8 hybrid powertrain with 887 hp. A 2015 Porsche 918 Spyder that has never been registered will be available at a Hong Kong auction running from April 2-5 and is expected to sell for between $1.5 million and $2 million. The 918 Spyder launched as one of the ‘hypercar holy trinity’ alongside the Ferrari LaFerrari and McLaren P1. While there are many low-mileage examples out there, few are thought to have been driven less than this one. Over the past decade, it has been driven less than 70 km (43 miles) and has been owned by a single person in Hong Kong. It has also never been registered for road use. The listing doesn’t specify how the car has racked up 70 km without being registered. Read: This Porsche 918 Is One Of Just 2 With A Gulf Oil Livery Nevertheless, this car i...
