Best Camshaft for a 6.0 LS Engine
The 6.0 LS engine is one of the most popular platforms for performance builds thanks to its strong iron block, larger displacement, and excellent aftermarket support. One of the most common upgrades performed on the 6.0 LS is installing a performance camshaft.
A camshaft upgrade allows the engine to move more air, which directly increases horsepower and torque. Because the 6.0 already has greater displacement than the 5.3, cam upgrades often deliver even larger performance gains.
This is why cammed 6.0 LS engines are extremely common in high-performance builds and LS swapped Chevy C10 trucks.
What a Camshaft Upgrade Does
The camshaft controls when and how long the engine’s valves open and close. A performance camshaft changes valve timing and lift to improve airflow through the engine.
A cam upgrade typically provides:
- Increased horsepower and torque
- More aggressive engine idle
- Improved high-RPM performance
- Better airflow through the engine
Because LS engines respond very well to airflow improvements, cam upgrades often deliver significant performance increases.
Horsepower Gains from a 6.0 LS Cam Upgrade
A camshaft upgrade is widely considered one of the best performance upgrades for LS engines.
Typical gains include:
- 60 – 120 horsepower increases
Many cammed 6.0 LS builds produce between 450 and 520 horsepower when paired with proper airflow upgrades.

Popular Camshaft Options for 6.0 LS Builds
Stage 1 Cam
Stage 1 cams offer moderate performance gains while maintaining smooth drivability. These cams are commonly used in daily driven trucks.
Stage 2 Cam
Stage 2 cams are the most popular option for performance builds. They provide strong horsepower gains and produce the classic aggressive cammed idle that many LS builders want.
This setup is extremely common in LS swapped C10 trucks.
Stage 3 Cam
Stage 3 cams provide maximum naturally aspirated performance but may require additional supporting modifications and professional tuning.
Supporting Upgrades for Cam Installations
Cam upgrades usually require additional components to ensure proper valve control and engine reliability.
- Upgraded valve springs
- Pushrods
- Timing components
- ECU tuning
These components help ensure the engine operates safely at higher RPM.
Pairing Cam Upgrades with Airflow Improvements
Cam upgrades work best when paired with additional airflow upgrades.
Common supporting upgrades include:
- Long tube headers
- High-flow exhaust systems
- Upgraded intake manifolds

Real Builder Insights from the LS Community
Across communities like LS1Tech, Sloppy Mechanics, and Reddit’s r/projectcar, many builders say the cam upgrade is the most impactful modification for unlocking the potential of a 6.0 LS engine.
Many experienced builders recommend starting with a Stage 2 cam paired with long tube headers and proper ECU tuning.
Builders also frequently mention that the 6.0 produces stronger low-end torque than the 5.3, which makes cam upgrades particularly effective in trucks.
Another commonly shared insight is that the distinctive “cammed LS chop” heard in many performance builds is largely created by camshaft design.
Common Camshaft Upgrade Mistakes
- Skipping ECU tuning after cam installation
- Using stock valve springs with aggressive cams
- Installing cams that are too large for street builds
- Ignoring supporting airflow upgrades
Choosing the right cam profile for the intended use of the vehicle helps maintain reliability and drivability.
Builder Tip
Many experienced builders install cam upgrades during LS swaps while the engine is already out of the vehicle. This makes installation easier and saves labor.
Quick Summary
A camshaft upgrade is one of the most effective ways to increase horsepower in a 6.0 LS engine. Many cammed builds produce between 450 and 520 horsepower when paired with proper airflow upgrades.
Stage 2 cams remain the most popular choice because they deliver strong power gains while maintaining good street drivability.
