1. COMP Cams 12-673-4 Xtreme Energy Cam Kit: Top Pick for High-RPM Power
The COMP Cams 12-673-4 Xtreme Energy cam kit is a popular choice for street/strip builds aiming for high-RPM power. In our evaluation, the kit delivers strong performance gains from 3000 to 6500 RPM, making it ideal for cars with stall converters and 3.55+ gears. Owners report noticeable throttle response and a lumpy idle that signals serious power.
However, this kit is not for stock engines. It requires upgraded valve springs, hardened pushrods, and a higher stall converter. Those with near-stock drivetrains should consider a milder stage 2 cam. Also, the aggressive profile can lead to increased valvetrain noise and wear if not properly tuned.
- Aggressive lobe profile for maximum top-end horsepower
- Includes cam, lifters, springs, retainers, and timing chain
- Proven design with thousands of successful builds
Pros: Excellent power gains above 3000 RPM; High-quality components from a trusted brand
Cons: Requires upgraded valvetrain and torque converter
2. Edelbrock 2106 Performer RPM Cam Kit: Best Balanced Street/Strip
The Edelbrock 2106 Performer RPM cam kit offers a balanced approach for those who want stage 3 performance without sacrificing daily drivability. Based on owner feedback, it provides a broad power band from 2000 to 6000 RPM, making it suitable for street-driven cars with 3.08 to 3.55 gears. The kit includes everything needed for installation, simplifying the build process.
That said, this cam is milder than other stage 3 options, so maximum top-end power may be lower. It also still requires upgraded springs and pushrods for reliability. If you are building a dedicated race car, you might prefer a more aggressive profile. We recommend this for enthusiasts who want a fun street car that can handle occasional track days.
- Designed for Edelbrock Performer RPM intake manifolds
- Smooth power curve from 2000 to 6000 RPM
- Includes cam, lifters, and timing chain
Pros: Good street manners with strong mid-range; Comprehensive kit with matched components
Cons: Not as aggressive as some stage 3 cams
3. Lunati 10120703 Voodoo Cam Kit: Best Value for Power
The Lunati Voodoo cam kit offers an aggressive lobe profile at a competitive price, making it a value leader in our comparison. Owner feedback indicates excellent power gains from 3000 to 6500 RPM, especially with higher compression ratios (10.5:1+). The kit includes necessary valvetrain components, though some users upgraded to heavier springs for reliability.
However, the fast ramp rates can increase valvetrain stress and noise. It also demands careful tuning to prevent detonation, especially with pump gas. If you are not comfortable with engine tuning or have a low-compression engine, this kit may be too aggressive. We suggest it for experienced builders on a budget.
- Voodoo lobe design for fast ramp rates
- Includes cam, lifters, springs, and retainers
- Good for high-compression builds
Pros: Aggressive lobes produce strong power; Affordable compared to competitors
Cons: Requires precise tuning to avoid detonation
4. Summit Racing SUM-8500 Cam Kit: Budget-Friendly Option
The Summit Racing SUM-8500 cam kit is designed for budget-conscious builders who want stage 3 performance without breaking the bank. Based on owner reviews, it offers a noticeable power increase over stock, with a lumpy idle and good mid-range pull. The kit is complete and easy to install, making it a popular entry-level choice.
However, the included valve springs are often considered marginal for sustained high-RPM use. Many owners replaced them with aftermarket springs after failures. Also, the cam profile is on the milder side for stage 3, so maximum horsepower may disappoint serious racers. We recommend this kit for low-budget street builds where absolute power is not critical.
- Affordable kit for budget builds
- Includes cam, lifters, and timing set
- Mild stage 3 profile with decent street manners
Pros: Low cost for a complete kit; Good for beginners on a budget
Cons: Lower quality springs may need replacement; Not as powerful as premium cams
5. Howards Cams 120015-12 Cam Kit: Durable for Street/Strip
The Howards Cams 120015-12 is a robust stage 3 kit built for durability in street/strip applications. In our research, the cam core and components are known for longevity, with many owners reporting thousands of trouble-free miles. The aggressive lobes deliver impressive power from 3500 to 7000 RPM, making it suitable for high-performance builds with stall converters and steep gears.
However, the cam has a very rough idle and minimal low-end torque, making it unpleasant for daily driving. It also requires a high-stall torque converter (3000+ RPM) and proper valvetrain geometry. If you need a cam that can handle occasional track abuse and still be street-driven, this is a good choice, but it is not for beginners or street cruisers.
- Heavy-duty cam core for longevity
- Includes high-quality lifters and springs
- Works well with 10:1+ compression
Pros: Excellent durability and warranty; Strong power above 3500 RPM
Cons: Harsh idle and poor low-end torque
6. Crower 00245 Cam Kit: Premium Race-Ready Kit
The Crower 00245 cam kit is a premium race-oriented stage 3 cam designed for serious horsepower seekers. Based on manufacturer specs and owner feedback, it delivers outstanding power above 4000 RPM, with a peak near 7000 RPM. The kit includes top-tier components that can handle sustained high-RPM use, making it a favorite among dedicated racers.
However, this kit is not for the faint of heart. It requires a high-stall converter (4000+ RPM), race headers, and extensive engine work. The cost is significantly higher than other kits, and the extreme idle and low-end loss make it impractical for street use. If you are building a full-race small block, this is an excellent choice, but street enthusiasts should look elsewhere.
- Race-proven cam profile for maximum power
- Includes premium springs, retainers, and lifters
- Designed for high-RPM operation (6500+)
Pros: Exceptional top-end horsepower; High-quality components from Crower
Cons: Very expensive and requires extensive modifications
7. Chevrolet Performance 24502586 Cam Kit: Factory-Backed Reliability
The Chevrolet Performance 24502586 cam kit is a factory-engineered option for those who prioritize reliability and ease of installation. Based on our research, it offers a mild stage 3 profile that works well with stock components, making it a good upgrade for mild street builds. The kit is complete and backed by GM, giving peace of mind to owners.
However, this cam is the least aggressive in our comparison, with lift under .500. Power gains are modest, and it may not satisfy those seeking a true stage 3 experience. It also lacks the high-RPM punch of aftermarket cams. If you want a simple upgrade with factory support, this is a solid choice, but performance enthusiasts will likely be underwhelmed.
- Genuine GM performance cam kit
- Designed for 350 HO crate engines
- Includes cam, lifters, and timing chain
Pros: Reliable and easy to install; Good warranty and support
Cons: Mild for a stage 3 cam; Limited power gains compared to aftermarket
Frequently Asked Questions
What supporting modifications are needed for a stage 3 cam in a 350 small block?
Stage 3 cams require upgraded valve springs, hardened pushrods, and often a higher stall torque converter (2500-3500+ RPM). You will also need a tune to optimize air-fuel ratios and timing. Additionally, consider upgrading the fuel system, headers, and intake manifold to match the cam’s airflow demands.
Will a stage 3 cam kit work with a stock 350 engine?
Technically it can be installed, but it is not recommended. A stock 350 with low compression (8.5:1) and a stock torque converter will result in poor low-end torque, a rough idle, and potential drivability issues. You will likely need a higher stall converter and higher compression pistons to see benefits.
What is the difference between stage 1, 2, and 3 cam kits?
Stage 1 cams offer mild performance gains with stock drivability. Stage 2 cams provide a noticeable power increase with slightly rough idle. Stage 3 cams are aggressive, with high lift and duration, delivering strong top-end power but requiring supporting modifications and sacrificing low-end torque and idle quality.
How do I choose the right cam kit for my build?
Consider your engine’s compression ratio, rear gear ratio, torque converter stall speed, and intended use (street, strip, or track). A cam with 110-112 LSA is common for street/strip. Higher lift and duration suit high-RPM builds. We recommend consulting with the cam manufacturer or a professional engine builder.
Can I install a stage 3 cam kit myself?
Installation requires mechanical skills, including degreeing the cam, checking valve clearance, and replacing timing chain and lifters. It is possible for experienced DIYers, but beginners should consider professional installation to avoid damaging the engine. Proper break-in procedures are essential.
