5 Pushrod Engines That Still Outperform Modern Turbo Technology
Compare the performance of classic pushrod engines with modern turbo technology.
1History and Advantages of Pushrod Engines
Pushrod engines have been used in the automotive industry for over a century. Their camshaft-in-block design makes them shorter, lighter, and simpler. Fewer moving parts mean lower maintenance costs. Brands like Chevrolet still use pushrod V8s in models like the Corvette and Camaro.
2The Rise of Turbocharged Engines
Emission regulations and the shift toward smaller engines have led engineers to adopt turbocharged units. Turbos offer more power and efficiency from smaller displacements. However, pushrod engines still outperform turbos in some performance metrics, sparking debates among car enthusiasts.
3Dodge Challenger SRT Demon 170
The Dodge Challenger SRT Demon 170 produces 1,025 horsepower with its supercharged 6.2L HEMI pushrod V8. On E85 fuel, output increases even further. Compared to turbocharged rivals, the Demon 170's 8.91-second quarter-mile time leaves even electric hypercars in the dust.
4Chevrolet Performance ZZ632/1000
Chevrolet's 10.4L ZZ632 Big Block is a naturally aspirated pushrod V8 that delivers 1,004 horsepower. Its CNC-machined aluminum heads and symmetrical port design stand out. Chevrolet validated its durability with 200 dyno tests. It clocks an impressive 8.98-second quarter-mile in drag simulations.
5Corvette ZR1's Supercharged LT5 Engine
The Corvette ZR1's supercharged LT5 pushrod V8 produces 755 hp and 715 lb-ft of torque. It combines direct and port injection systems. The ZR1 hits 0-60 mph in 2.9 seconds and completes the quarter-mile in 10.6 seconds. The LT5 remains the most powerful pushrod engine in a front-engined Corvette.
6Hellcat HEMI V8 Performance
Dodge's Hellcat HEMI V8 generates 707 horsepower with its supercharged pushrod design. Used in Challenger and Charger models, the Hellcat offers more consistent performance than turbocharged rivals in drag races. Its simpler design also reduces maintenance costs.
7Durability of Pushrod Engines
Pushrod engines are more durable and long-lasting due to fewer moving parts. Unlike turbos, they aren't exposed to high pressures and temperatures, making them more reliable in tough conditions. This advantage is especially notable in off-road and commercial vehicles.
8Limitations of Turbocharged Engines
While turbocharged engines deliver high power from small displacements, they have drawbacks. Issues like turbo lag can negatively impact driving dynamics. High pressures and temperatures may also shorten engine life. Pushrod engines offer more consistent power delivery.
9The Future of Pushrod Engines
Even as the auto industry shifts toward EVs, pushrod engines remain relevant. They are still preferred in performance and durability-focused segments. Brands like Chevrolet and Dodge continue to refine pushrod designs, ensuring their place in automotive history.
