COMP Cams 12-242-2 Xtreme Energy 224/230
The 12-242-2 is a good all-around choice for street machines using a stock converter and with a 1,600-5,800 RPM operating range. It delivers a 224/230 duration at .050″ and a 110-degree lobe separation, making it suitable for reliable idle with improved mid-range torque. Best for buyers seeking a balance of street drivability and noticeable performance gains without heavy cam swap requirements.
Who it’s best for: daily drivers with mild performance goals, stock-to-mild long-tail wagons, and enthusiasts who want improved power without sacrificing low-RPM manners. Caution: may require fine-tuning to optimize performance with certain ignition curves and exhaust setups.
Engine Pro Chevy SBC 350 5.7L HP RV 420/433 Lift
This cam from Engine Pro emphasizes versatility across Chevy SBC engines from 1957 to 1995, with 420/433 lift and a design that favors improved low-end power and smoother idle. It’s well suited for highway cruising and towing duties where steady power at lower RPM is valued. Best for: owners wanting an easy upgrade path that broadens torque without sacrificing daily drivability.
Consideration: verify engine code compatibility for your build and note that performance gains depend on supporting components like timing, cam bearings, and lifters.
COMP Cams CL12-246-3 Xtreme Energy 230/236
This hydraulic flat cam provides a strong mid-range torque and robust throttle response with a 230/236 duration at .050″ and a 110-degree lobe separation. The recommended 1,800-6,000 RPM operating range makes it a better fit for street performance than a pure towing setup. Best for: performance-minded drivers who want noticeable acceleration improvements without high stall speeds.
Limitation: higher stall and gearing may be needed to maximize power; ensure your torque converter and intake are aligned with this cam profile.
COMP Cams 12-234-2 Xtreme Energy 212/218
The 12-234-2 offers strong low-end to mid-range torque with a reliable idle, featuring 212/218 duration at .050″ and a 110-degree lobe separation. Operating range from 1,000 to 5,200 RPM makes it a practical choice for daily drivers who want better off-idle response. Best for: those prioritizing a steady, broad torque curve and a smooth idle over peak horsepower.
Caution: may require a more aggressive exhaust or compression for maximum gains; compatibility with stock readers and exhaust is important for best results.
COMP Cams CL12-602-4 Big Mutha’ Thumpr 243/257
The Big Mutha’ Thumpr series delivers a highly aggressive idle and robust street/strip performance with 243/257 duration at .050″ and a 107-degree lobe separation. The 2,500-6,400 RPM operating range suits optimized launch conditions and high-stall setups. Best for: enthusiasts seeking a loud, aggressive cam with strong mid-to-high RPM power.
Limitation: very rough idle can be undesirable for some street setups; consider exhaust and compression adjustments to balance noise with performance.
Buying Guide: Key Considerations For Choosing A Cam For 350 Engines
- Intended use: Determine whether you prioritize daily drivability, towing, or track capability. Cam profiles vary in idle quality, torque, and RPM range to match your goals.
- RPM range and torque curve: Align the cam’s operating range with your gearing, stall converter, and intake/exhaust setup for optimal response.
- Compression and fuel: Higher compression or forced induction can shift cam effectiveness. Match cam choice to your engine’s compression ratio and fuel system.
- Cam vs. supporting parts: Intake, exhaust, lifters, and timing chains affect performance. Ensure compatibility with your rebuild plan and maintenance budget.
- Idle quality and emissions: Some cams produce rough idle or higher exhaust emissions; consider these factors for street use and regulatory concerns.
- Vehicle weight and gearing: Heavier vehicles with lower gears may benefit from cams with broader torque at lower RPM, while lighter builds may leverage higher RPM efficiency.
Frequently Asked Questions
- What is the main difference between hydraulic flat tappet cams and other cam types?
– Hydraulic flat tappet cams use lifters to press on the cam lobe for smoother operation, typically requiring less maintenance than solid designs and offering good idle and driveability. - Will these cams require additional tuning?
– Yes. Cam changes usually require adjustments to ignition timing, fuel mapping, and possibly exhaust components to realize full gains. - Is a higher stall converter beneficial with cam upgrades?
– Often yes. A higher stall can improve throttle response and launch with cams designed for higher RPM use, but it depends on your overall setup. - Can I use these cams in stock engines without modifications?
– Some are designed for stock-to-mild builds; others require supporting upgrades. Always verify compatibility with your exact VIN, year, and engine code. - How do I choose between a broader torque range and a higher RPM peak?
– If you want better mid-range power for everyday driving, pick a cam with a wider torque band. For racing or high-speed uses, a cam with higher RPM efficiency may be preferable. - Do these cams affect engine reliability?
– Any cam upgrade can affect valve train dynamics and fuel delivery; ensure the lifters, bearings, and timing components are suitable for the chosen profile and maintenance plan.
