These are the most likely candidates to receive V8 power for years to come.
The information regarding the LS small-block V8 was gathered from various sources, mainly General Motors press outlets and historical press materials. This focus on the LS stems from a discussion where we asked readers to identify which brand they most associate with the V8, and GM emerged as the favorite.
The LS V8’s Enduring Popularity
Factors Behind the LS’s Strong Start
- It capitalized on the popularity of the Chevrolet 350 CID engine
- General Motors integrated it into a wide range of vehicles
- It boasts a straightforward design
We’re not here to undermine the LS V8’s reputation for providing affordable power and ease of use. However, it’s important to recognize that the LS V8 owes much of its success to its predecessor, the Chevrolet small-block 350 CID, which laid the groundwork even before the LS was imagined. The original small-block traces its origins to the mid-1950s, designed for the C1 Corvette and the Chevrolet Bel Air.
As the years passed, Chevrolet expanded its use of the engine across various models, developing different variants of the small-block with varying displacements and power outputs. Some were tailored for utility in Chevrolet C/K pickup trucks while others were engineered for high performance, as seen in the Corvette. In summary, the Chevy small-block quickly became known for its versatility.
10 Cars Powered By General Motors’ Most Reliable V8 Engine
GM and V8 engines are a match made in heaven, and one V8 has powered some mighty impressive machines.
By the mid-1990s, the old small-block engine was falling behind the times. It was clear that a new solution was needed. Consequently, General Motors embarked on a redesign that resulted in the LS V8, which debuted in the 1997 Chevrolet Corvette C5. Just two years later, the LS was integrated into multiple vehicle platforms, including the Chevrolet Silverado and Camaro.
Enthusiasts quickly recognized the advantages of the LS small-block, especially its simplicity in repairs and its durability. Additionally, it demonstrated significant adaptability to modifications without requiring extensive overhauls, making it an attractive option for those swapping engines in non-GM models. The affordability of parts also appealed to DIY enthusiasts looking to save on repairs.
The Popularity of LS Swaps
If you’re involved in the tuning community or merely an interested observer, you’ve likely heard about LS swaps. This practice is prevalent, as certain vehicles are more frequently swapped than others. The LS engine’s compact design allows it to fit into a variety of vehicles, expanding its compatibility.
For instance, the Mazda Miata is a prime candidate for the LS swap, benefiting immensely from the added power. One of the more significant costs associated with this swap can be the driveshaft modifications. Other frequently swapped vehicles include the Nissan 300ZX and, humorously, the Fox Body Ford Mustang.
Another factor contributing to the popularity of LS swaps is the affordability of the engine. You can source an engine from a car with exterior damage, or find used options on platforms like Facebook Marketplace. A brand-new base LS3 motor with over 400 horsepower typically costs around $6,600. Pair that with a worn-out first-generation Miata, and you could have a formidable performance car for under $20,000, including gearbox and modifications.

High Power, Low Cost
In addition to being easy and inexpensive to swap, the LS engine enjoys the benefit of a vast parts catalog and numerous manufacturers creating components for it. This competition in the market results in lower parts prices. For example, a stock intake manifold for an LS 5.3-liter V8 generally costs around $400. In contrast, sourcing an intake for an M156 Mercedes-Benz V8 can cost more than double that.
When deciding to build or purchase a vehicle with an LS engine, it’s crucial to consider the costs of replacement parts. Many buyers of older vehicles intend to handle repairs themselves. Cost efficiency is essential for those without substantial financial resources, and the GM LS V8 proves to be an economical engine to operate, making it perfect for swaps, modifications, and everyday use.
The Well-Deserved Status of the General Motors LS V8
Initially, this article may have suggested some skepticism regarding the LS V8’s rightful place at the top. However, it undeniably earns its status and has secured it through merit. Its legacy is clear, having paved the way for other automakers to develop their own everyday V8 engines. Without the Chevrolet small-block, not only would the LS engine likely not exist, but the entire automotive landscape could look very different today.
Looking ahead, General Motors plans to phase out the LS engine. About a year ago, they announced they are developing its successor. Although specific details remain sparse, we know that the new engine will be featured in the upcoming C9 Corvette, anticipated to be revealed by 2028. In the meantime, car enthusiasts will continue to enjoy the LS engine and the numerous advantages it offers.
