More Details on Our Top Picks
Genuine COMP CAM 12-602-4 Big Mutha Thumpr 243/257 Camshaft for Chevrolet SBC
This camshaft stands out for its aggressive sound and high-RPM performance, making it ideal for street racers and drag enthusiasts who want maximum top-end power. Compared to the Michigan Motorsports Stage 2 LS3 Drift Camshaft, it offers more radical duration and lift, delivering a raw, race-inspired experience. However, this comes at the cost of low vacuum and rough idle, which could impact daily drivability. It requires a high stall converter and deep gears to truly shine, making it less suitable for street-driven vehicles focused on comfort. The included high-performance lifters, double roller timing set, and push rods provide a comprehensive upgrade for serious builds.
Pros:- Provides aggressive, race-inspired sound and performance
- Maximizes airflow with high lift for big horsepower
- Includes comprehensive high-performance components
Cons:- Produces low vacuum, affecting power brakes
- Requires high stall converter and deep gears for optimal use
- Rough idle due to radical duration and overlap
Best for: Performance enthusiasts seeking race-level power and sound, with a dedicated track or drag strip in mind.
Not ideal for: Daily drivers prioritizing smooth idle and fuel economy, as this cam produces significant idle roughness and low vacuum issues.
- Lift:.500/.486″
- Duration:243/257 @ .050″
- Application:Chevrolet SBC 262-400
- Compatibility:Gen 1 SBC V8
- Stall Converter:2800+ RPM
- Headers:Required
- Push Rod Length:7.794″
Our verdict“This camshaft is perfect for racers and enthusiasts who prioritize power and sound over comfort and idle smoothness.”
Michigan Motorsports Stage 2 LS3 Drift Camshaft Kit for Rectangle Port LS 6.0/6.2
This kit makes the most sense for drivers who enjoy a mix of streetability and drifting, offering a balanced powerband with a lopey idle. Compared to the more aggressive Big Mutha Thumpr, it provides a smoother operation suitable for daily use, with quality components like titanium retainers and chromoly pushrods. The 226/238 duration and .629/.615 lift strike a good balance between performance and drivability, but it’s not ideal for high-horsepower builds that require more aggressive cams like the Stage 4 LS Burnout Camshaft. Installation may need professional tuning, especially for optimal power gains. Its design limits compatibility to certain engine types, so not all LS engines will fit without modifications.
Pros:- Strong powerband suitable for daily driving and drifting
- Includes high-quality components like titanium retainers
- Delivers a lopey idle with good street manners
Cons:- Designed for specific engine types, limiting compatibility
- Installation may require professional tuning
- Performance gains depend on supporting modifications
Best for: Drivers who want a reliable, daily-friendly cam that can handle drifting and spirited street driving without sacrificing smoothness.
Not ideal for: Builds focused solely on maximum horsepower or burnout performance, as this cam prioritizes balanced drivability over extreme power.
- Camshaft Duration:226/238
- Camshaft Lift:.629″/.615″
- LSA:111
- Spring Diameter:.660″
- Pushrod Length:7.400″
Our verdict“This cam is well-suited for daily drivers who want a reliable, fun, and drivable LS3 upgrade.”
COMP Cams 54-602-11 Big Mutha’ Thumpr Hydraulic Roller Cam for GM LS GEN III/IV
This cam excels in delivering a broad torque curve and high horsepower, especially when paired with aftermarket gears and converters. It offers a significant step up over milder cams like the Texas Speed Stage 1 LS3, with a duration of 235/249 and lift of .573/.558. The rough idle and high compression requirements make it less suitable for daily drivers seeking comfort, but it provides a noticeable performance boost for street/strip setups. Compared with the Stage 3 LS Burnout Camshaft, it offers a wider RPM operating range, making it versatile for various performance builds. It’s a strong choice for enthusiasts wanting maximum power without sacrificing street usability entirely.
Pros:- Delivers excellent horsepower and broad torque curve
- Suitable for street and strip applications
- Compatible with GM LS GEN III/IV engines
Cons:- Requires high compression (9.5:1) and aftermarket upgrades
- Produces a very rough idle
- Designed mainly for performance enthusiasts, not quiet operation
Best for: Street and strip enthusiasts seeking a broad powerband and high horsepower potential with a decent RPM range.
Not ideal for: Casual drivers or those sensitive to rough idle and high compression demands, as it leans toward performance over comfort.
- Cam Duration at .050″:235/249
- Valve Lift:0.573/0.558 inches
- Lobe Separation Angle:109 degrees
- Application:GM LS GEN III/IV
- Operating Range:2,600-6,800 RPM
Our verdict“This cam is an excellent choice for performance-minded drivers wanting a broad powerband with robust top-end gains.”
TSP Texas Speed Stage 3 LS3 N/A Camshaft Kit with Dual Springs, Retainers, Hardened Pushrods, and Gasket
This complete kit makes a compelling choice for those aiming to maximize naturally aspirated power while maintaining street drivability. Compared to the Michigan Motorsports Stage 2 LS3 Drift Camshaft, it offers a slightly longer duration (231/246) and higher lift (.640/.615), translating into more horsepower and torque gains—up to +88 HP and +28 TQ. The inclusion of dual springs, hardened retainers, and chromoly pushrods reduces the risk of valve float at high RPM. However, the necessity of a minimum 3,200 RPM stall converter for automatic transmissions limits some street setups, and installation generally requires professional tuning. Its compatibility is focused on specific LS models from 2010 to 2015, so it’s not a universal upgrade.
Pros:- Up to +88 HP and +28 TQ gains
- Complete kit with all necessary components
- Designed for streetable high-performance engines
Cons:- Requires a high stall converter for best results
- Installation may need professional tuning
- Limited to specific engine models and years
Best for: Performance enthusiasts building naturally aspirated LS3 engines for maximum streetable horsepower.
Not ideal for: Budget-conscious or casual users who don’t want to invest in professional tuning or specific supporting parts, like high stall converters.
- Camshaft Duration:231/246
- Camshaft Lift:.640/.615
- LSA:111
- Compatibility:LS2, LS3, LSA, L92, L99, L76
- Application:2010–2015 Camaro SS, Corvette C6, GXP
Our verdict“This kit is ideal for enthusiasts seeking maximum naturally aspirated power in a street-ready LS3 build.”
Michigan Motorsports Stage 4 LS Burnout Camshaft with Springs, Titanium Retainers, Chromoly Pushrods, and Gasket Kit
This cam is designed for serious burnout and high-RPM performance, offering a radical idle and tire-shredding capabilities. Compared to the Stage 3 LS3 N/A Camshaft, it features more aggressive duration (238/250) and similar lift, creating an unmistakable choppy idle and maximum top-end power. It’s built for engines that can handle its high RPM range, making it less suitable for daily drivers or street cruisers. Its broad application across GM LS engines from 5.3L to 6.2L ensures versatility for competition builds. However, primarily intended for burnout and racing scenarios, it may not deliver the smoothness or reliability expected in daily street driving.
Pros:- Delivers extreme lope and tire-shredding power
- Optimized for high-RPM horsepower
- Compatible with a wide range of GM LS engines
Cons:- Primarily for burnout and competition use
- Not suitable for daily street use
- Requires supporting high-RPM components
Best for: High-performance racers and burnout enthusiasts seeking maximum top-end horsepower and a radical idle.
Not ideal for: Everyday drivers or street users prioritizing smoothness, fuel efficiency, and low idle noise.
Our verdict“This cam is tailored for serious performance builds focused on burnout and high-RPM power, not daily street comfort.”
E1841P Sloppy Stage 3 Camshaft Kit .595″ with Springs, Pushrods, Lifters Set for Chevrolet GMC LS Engines
The Sloppy Stage 3 Camshaft Kit stands out for delivering a significant power increase and improved throttle response, especially compared to milder options like the BTR LS3 Stage 1. Its complete package includes high-quality springs, lifters, and gaskets, making it ideal for serious enthusiasts who want a reliable, ready-to-install upgrade. The durable materials and 1-year warranty add confidence, but this kit is geared toward seasoned builders due to its demanding installation process.

- Durable high-strength materials ensure longevity
- Complete kit with all necessary components
Cons:- Designed primarily for performance-focused builds
- Installation may require professional expertise
- Limited compatibility to certain LS engine models
Best for: Performance enthusiasts looking to maximize power and throttle response on their LS engine with professional installation experience.

- Camshaft Size:.595″
- Includes:Camshaft, valve springs, oil seals, gasket, screw
- Compatibility:Chevrolet and GMC LS engines from 1997-2013
- Warranty:1 year
Our verdict“This kit is best suited for experienced builders aiming for maximum performance gains on compatible LS engines.”
BTR Brian Tooley Racing Twin Turbo Stage 1 LS Camshaft for Gen III/IV 4.8L-6.2L Engines
The BTR Twin Turbo Stage 1 Camshaft excels in turbocharged street setups, especially for engines like the 5.3L or 6.0L with cathedral port heads, surpassing naturally aspirated cams like the Texas Speed LS3 Stage 1 in turbo applications. It’s optimized for small turbos (58mm-66mm), making it ideal for street-driven turbo builds seeking quick spool and mid-range power.

- Bolt Pattern:3 Bolt
- Fits:1997-2013 LS engines, 4.8L-6.2L
- Application:Twin turbo, street use, small turbos
Our verdict“This cam offers excellent gains for turbocharged street engines but isn’t suitable for NA applications without further upgrades.”

- Application:4.8L-6.2L cathedral-port LS engines
Our verdict“This cam is best for seasoned truck builders aiming for aggressive airflow and sound enhancements.”
BTR Brian Tooley Racing LS3 Stage 5 Camshaft (Camshaft Only)
This Stage 5 LS3 camshaft from Brian Tooley Racing stands out for enthusiasts seeking over 600hp with high-performance ported heads and intake systems. Compared to the Texas Speed 228R, it offers even more aggressive specifications tailored for maximum effort NA applications, though it demands a valve clearance cut for stock pistons and a 3200+ rpm converter for automatic setups. Its extensive testing and proprietary lobes ensure reliability at high power levels, but it’s not suitable for mild or stock engines.

- Bolt Pattern:3 Bolt
- Application:NA high-performance engines
Our verdict“This camshaft makes the most sense for experienced enthusiasts targeting maximum NA horsepower with supporting upgrades.”
Texas Speed TSP Stage 3 Low Lift Camshaft for Vortec Truck Engines
This Stage 3 Low Lift Camshaft from Texas Speed is tailored for 4.8, 5.3, and 6.0 Vortec engines, providing a solid balance of power and drivability. Unlike the more aggressive BTR Stage 5, it emphasizes a lower lift (.550″) and a 112 LSA that keep it manageable for daily use. Its power gains are substantial but not overwhelming, making it a practical upgrade for truck owners wanting more punch without sacrificing reliability. It requires tuning, similar to the TSP 228R, but is designed to work well with factory components and is easier to install than high-strung race cams.

E-1840-P Sloppy Stage 2 Camshaft for LS-Series Engines
The Sloppy Stage 2 LS camshaft offers a straightforward upgrade for LS engines, designed to improve performance and durability. It’s comparable to the Texas Speed 228R but focuses on a more moderate lift of .585″ and a lobe separation of 112°, making it a good choice for those who want better power without the aggressive idle or tuning demands of high-end cams. Its OE-quality manufacturing ensures reliability, but it’s not suitable for engines with AFM/DOD systems.

Texas Speed TSP 228R 228/228 .600″/ .600″ 112 LSA Camshaft for LS Engines
This Texas Speed 228R camshaft offers a solid increase in horsepower, roughly 5-7 HP over stock, with a duration of 228/228 and .600″ lift. It’s more aggressive than the Stage 3 Low Lift but less extreme than the Stage 4 F-35, providing a good compromise for street enthusiasts. Its design to be beehive & double valve spring friendly simplifies upgrades, and it delivers a noticeable power bump with a rougher idle that may require tuning. Compared to the more aggressive Stage 4 F-35, it offers a milder profile suitable for daily drivers who want more power without sacrificing too much idle quality.

The Stage 4 F-35 camshaft from Texas Speed is designed for high-performance LS3 engines, offering aggressive durations of 235/248 and high lift (.649″/.615″) for maximum high-RPM power. Compared to the Stage 5 BTR cam, it’s tailored for race or high-horsepower street builds, with a 111 LSA to promote high airflow and top-end power. It demands supporting upgrades such as a valvetrain, induction, and precise tuning, making it less suitable for daily drivers.

How We Picked
To determine the best camshafts for Chevy LS3 street applications, I evaluated each product based on performance potential, street usability, durability, and value. I considered profiles that offer a noticeable power increase without sacrificing too much idle quality or drivability. Compatibility with stock or mildly upgraded engines was a key factor, as well as the inclusion of essential components like springs or retainers. The ranking reflects a balance between aggressive performance and everyday usability, prioritizing options that suit a broad range of street enthusiasts while acknowledging that more extreme cams may suit dedicated racers better.Factors to Consider When Choosing Camshaft Chevy Ls3 Street
Selecting the right camshaft for your LS3 street build involves balancing several factors. Beyond raw power, considerations like idle quality, fuel efficiency, and compatibility with existing engine components influence your choice. Understanding these factors can prevent costly mistakes and ensure your build meets your expectations for daily driving or spirited street use.Performance Goals
Define what you want from your engine—whether it’s more torque for cruising or higher RPM horsepower for spirited driving. Aggressive profiles provide more power but can lead to rough idling and increased fuel consumption. Less aggressive cams offer smoother operation and better reliability but may sacrifice some top-end performance.
Compatibility and Build Stage
Ensure the camshaft matches your engine’s current setup and modifications. Some cams are designed for naturally aspirated engines, while others suit forced induction setups. Matching your cam to your engine’s compression ratio, valve train, and supporting components prevents issues like valve float or insufficient spring pressure.
Lifter and Spring Requirements
High-lift or duration cams often need upgraded valve springs and lifters. Installing a cam without these upgrades can cause valve float at high RPMs or damage to the valvetrain. Factor in the cost and complexity of these additional parts to get a complete, reliable upgrade.
Idle and Driveability
Consider how the cam profile affects idle quality and throttle response. Mild cams tend to idle smoothly and are better suited for daily drivers, whereas aggressive profiles can produce a lopey idle and more noise. Think about your comfort level with increased engine noise and roughness.
Budget and Value
Camshaft prices vary widely, often reflecting performance level and included components. While investing in a high-quality, well-matched cam can improve longevity and performance, overspending on features you don’t need might not be cost-effective. Balancing your budget with your performance goals is key.
Frequently Asked Questions
Can I install a more aggressive camshaft on my stock LS3 engine?
Installing a more aggressive camshaft on a stock LS3 is possible but requires careful consideration. You may need to upgrade valve springs, retainers, and possibly the ECU tune to prevent issues like valve float or poor idle. The increased duration and lift will also impact fuel economy and driveability, so it’s important to match your expectations with the modifications and supporting components.
How does a camshaft affect street performance and daily driving?
A camshaft influences torque, horsepower, idle quality, and fuel economy. Mild cams provide smooth operation and reliability, ideal for daily drivers. More aggressive profiles increase power at higher RPMs but can cause rough idling and reduced low-end torque. The right choice depends on your priorities—whether pure performance or balanced street use.
Is it necessary to upgrade valve springs when changing my camshaft?
Upgrading valve springs is often necessary with high-lift or high-duration cams to prevent valve float and ensure stability at higher RPMs. Failing to do so can lead to engine damage or performance issues. The cost of springs and installation should be factored into your overall upgrade budget, especially if you’re aiming for maximum performance.
What is the best camshaft for a budget-friendly LS3 street build?
For those on a budget, selecting a camshaft that offers a noticeable power gain without extensive supporting modifications is ideal. Cam profiles like the Texas Speed TSP Stage 1 or similar mild profiles provide a good balance of performance and affordability. Always ensure compatibility with your engine’s setup to avoid additional costs or complications.
Can I switch camshafts myself, or do I need a professional?
While some experienced DIY enthusiasts can replace a camshaft with the right tools and knowledge, it’s often best to have a professional handle the job. Proper timing, spring upgrades, and ensuring correct installation are critical to engine longevity and performance. Mistakes in installation can lead to costly damage, so weigh your skill level carefully.
Conclusion
For most street enthusiasts, the Genuine COMP CAM 12-602-4 Big Mutha Thumpr offers a solid balance of performance, sound, and streetability, making it the best overall pick. If you’re focused on cost-effectiveness, the TSP Stage 1 LS3 Camshaft provides good gains without breaking the bank. For those seeking the highest performance and are willing to invest in supporting upgrades, the Michigan Motorsports Stage 2 LS3 Drift Cam or Stage 3 LS3 N/A Cam are excellent choices. Beginners or daily drivers should prioritize mild profiles for smooth operation, while seasoned builders aiming for maximum power should consider more aggressive options with supporting components. Ultimately, your choice depends on your specific goals, budget, and willingness to upgrade other parts.
