Revisiting Classic Muscle Cars: Are Crate Engines Still Available for 1960s and 1970s Muscles?

Are you interested in revitalizing your classic muscle car from the 1960s and 1970s? Crate engines, which are factory-built and designed for easy installation, are available for these iconic vehicles. However, the availability and choice of these engines can vary. In this article, we will explore crate engines, specifically those from Chevrolet, and discuss whether they are still being manufactured or merely available as replacements.

Why Crate Engines?

Crate engines offer a convenient and cost-effective solution for enthusiasts looking to upgrade their classic muscle cars. They are typically available with a warranty, are pre-built to factory specifications, and are designed for bolt-in installation. This means less time and effort spent on assembly, allowing you to focus on the enjoyment of your vehicle.

Chevrolet's Crate Engines

Chevrolet GMPP: GM Performance Parts (GMPP) offers a range of crate engines for classic Chevrolets. If you own a Chevelle or a Camaro from the 55-2002 model range, you can get a crate engine that will match or exceed the power of the original. While these engines may not be exact "numbers matching" rebuilds, they generally provide more horsepower and torque than the older, smaller displacement engines. For instance, a 350 or a 383 cubic inch engine will offer a significant boost over the original 283 or 327 engines.

For those who prefer big-block V8s, Chevrolet offers several options. If you have a big-block, you can choose from the 454, 502, or 572 cubic inch engines. While the 396 and 427 cubic inch engines are less common, GMPP has occasionally offered the 427 in recent years. These engines can be a good choice if you're looking to increase the power output of your classic muscle car.

The State of Classic Engine Production

While crate engines are available, it's essential to understand that they are not made from the original engines from the 60s and 70s. Those engines have long since decayed and are extremely rare. If you hope to find an original engine from a classic muscle car, it's advisable to consult a specialist or a reputable restoring shop. However, remanufactured or rebuilt old engines can still be an option if you're willing to go through the process of restoration.

Current Availability: Modern foundries are casting new Chevrolet V8 engines, particularly the smaller displacement models. However, the foundry in Oshawa, Ontario, which once produced many of these engines, has closed down. If you have an engine casting that was made in Oshawa, it's likely to be from before the closure. The current casts are made in Mexico.

Replacement Engines: A Convenient Alternative

While crate engines offer a modern alternative, another option for those seeking to keep the original feel and authenticity of their classic muscle car is to buy a replacement engine outright. Many muscle car enthusiasts prefer to maintain the integrity of the original engine, but the availability of replacement engines can bridge the gap for those who desire modern performance.

Mopar and Summit Racing: If you're restoring a '70 Dodge Hemi Challenger, ordering a new 426 Hemi from Mopar Performance or a new engine for a '69 Corvette from Summit Racing can provide excellent results. These engines are designed to fit into the original engine compartments and come with most of the original accessories, ensuring a seamless installation process.

Modern replacement engines might include minor improvements and advancements over the original, but they will generally fit and work just as well. This option can be particularly appealing for those who want to keep their classic muscle car running as seamlessly as possible.

Conclusion

While crate engines offer an excellent means of upgrading and preserving the performance of classic muscle cars, it's important to understand their true nature. They are not made from the original engines from the 60s and 70s but are factory-built to mimic their performance. Additionally, replacement engines offer a convenient solution for those desiring modern performance while maintaining the original feel of their classic vehicle.

Whether you choose a crate engine or a replacement engine, remember that modern technology can enhance the driving experience of your classic muscle car, making it a true representation of its time.
