Camshaft Specifications
The Stage 3 NA V2 specs include:
227/24x .636/.636 111.5LSA227/24x\ .636/.636\ 111.5LSA
Additional specs:
- 3-bolt cam pattern
- Aggressive NA grind
- High-lift cam profile
This setup is engineered to maximize:
- Airflow
- Midrange torque
- High-RPM horsepower
- Naturally aspirated efficiency
Because naturally aspirated LS engines love airflow almost as much as LS owners love dyno charts.
Engineered for maximum power gains, this camshaft delivers a strong midrange pull, high-RPM performance, and a radical exhaust note, making it best possible for street and track builds.
Aggressive Choppy Idle
Let’s address the real reason many people buy this cam:
- The chop
The BTR Stage 3 NA Cam V2 delivers:
- Heavy idle lope
- Aggressive startup behavior
- Deep exhaust tone
- Violently cammed sound
Basically your LS starts sounding like it:
- Disagrees with emissions regulations
- Hates vacuum stability
- And may challenge nearby vehicles to street races automatically
Because calm idle quality is not part of the Stage 3 experience.
With its aggressive cam profile, the BTR Stage 3 NA Cam V2 maximizes airflow and efficiency, taking into consideration increased throttle response and extended powerband.
Naturally Aspirated Power Focus
Unlike turbo-focused camshafts, this BTR Stage 3 NA V2 is optimized specifically for:
- Naturally aspirated airflow
- High-RPM power
- Cylinder filling efficiency
- Strong top-end pull
Helping improve:
- Horsepower
- Torque
- Throttle response
- Midrange acceleration
Especially when paired with:
- Long tube headers
- Ported heads
- High-flow intakes
- Free-flowing exhaust systems
Because naturally aspirated LS builds survive entirely on airflow and attitude.
This camshaft is most suitable for high-revving naturally aspirated setups, requiring upgraded valve springs, pushrods, and supporting modifications to maintain the added lift and duration.
Excellent Midrange & Top-End Performance
The cam profile helps create:
- Stronger midrange torque
- Harder upper RPM pull
- Better acceleration
- Improved overall engine responsiveness
Perfect for:
- Roll racing
- Street driving
- Drag racing
- Weekend builds
Because LS engines pulling hard above 6,000 RPM is one of life’s simpler pleasures.
In case you are in search of a BTR camshaft that enhances performance, produces an unmistakable choppy idle, and unlocks more power out of your LS engine, the BTR Stage 3 NA Cam V2 is without equal upgrade

- Cammed Corvettes
- Street trucks
- LS swaps
- GTO builds

Not Exactly a “Quiet Daily Driver”
Let’s be realistic:
This cam is:
- Aggressive
- Loud
- Noticeably cammed
- Built for performance
Idle quality will absolutely:
- Be rougher
