Comp Cams 35-440-8 Magnum 220/220 Ford 5.0L
Features: Competition Cams is a trusted industry leader. Backed by manufacturer’s warranty. Delivers great performance.
Best for: Ford 5.0L enthusiasts seeking a well-rounded hydraulic roller that improves street power without excessive idle or wavering idle quality. This cam is a straightforward bolt-on for classic 5.0L builds with stock or mild non-EFI setups.
Why selected: It represents a balanced combination of lift and duration that yields noticeable mid-range and top-end response with reliable street manners. It’s straightforward for a mostly stock 302/5.0L engine.
Caution: Suitable for non-EFI or carbureted configurations; EFI compatibility varies by year and intake choice. Verify lifter compatibility with your existing valvetrain.
COMP CAM 32-431-8 MAGNUM 224/224 Retro Fit
Features: Includes lifters and timing set; high-effort street performance; redline retro fit lifters; 2,000–5,500 RPM range; .566″ lift, 110° LSA.
Best for: Ford 351C/351M/400 families that want a high-RPM punch with a strong mid-range surge while using a retro fit lifter package. Suitable for builds that don’t require major head work to wake up the engine.
Why selected: The Magnum profile is designed to deliver noticeable throttle response across a broad RPM band when paired with compatible hardware, making it a compelling choice for bolt-on performance seekers.
Caution: Requires precise installation torque and a compatible lifter/timing set; not ideal for severely stock, low-stall drivetrains without gearing changes.
Comp Cams 20-604-9 Computer Controlled 210/220 Chrysler Magnum
Features: High-performance cam for 360; 900-5,200 RPM range; 210/220 duration at .050″. 112 LSA.
Best for: Chrysler Magnum engines that need a robust mid-range with computer compatibility. Ideal for street/strip hybrids with aftermarket ECU tuning.
Why selected: It provides a strong torque curve and a wide operating window suitable for engines controlled by modern or semi-modern engine computers.
Caution: Some installations require software adjustments or sensor calibration to fully realize the gains.
COMP Cams 42-433-11 Xtreme Energy 236/242 Olds
Features: 2,200–6,000 RPM range; 236/242 duration at .050″; 110° LSA.
Best for: Oldsmobile big- and small-block builds where a strong mid-to-high range is desired and higher stall gears are feasible.
Why selected: The Xtreme Energy line emphasizes higher RPM capability with a drag-strip-friendly profile, while remaining usable on the street with adequate gearing and fuel supply.
Caution: Rough idle is noted in some setups; pairing with a higher stall converter and appropriate gearing is recommended to maximize driveability.
Comp Cams 20-744-9 XE 206/212 Chrysler Magnum
Features: Strong torque for 318; idle to 4,500 RPM; 206/212 duration at .050″. 112 LSA.
Best for: Chrysler Magnum engines that need an enduring, all-around cam with good low-end to mid-range response for daily driving and light towing.
Why selected: The XE series emphasizes efficiency and tractability, making it a practical choice for a daily driver that still wants improved power output and throttle response.
Caution: Computer-controlled setup may require ECU adjustments to avoid drivability issues and to unlock full potential.
Buying Guide: Key Considerations For Hydraulic Roller Cams
- Engine family compatibility: Ensure the cam is designed for your engine family and block type (Ford 5.0L, Chrysler Magnum, Oldsmobile variants, etc.).
- RPM range and intended use: Shorter-duration cams suit low-to-mid RPM street driving; longer-duration, higher-lift profiles excel at higher RPM and heads-up racing. Match to your gearing and stall torque.
- Lifter and timing set compatibility: Some cams ship with lifters or require specific retro-fit or timing sets. Verify compatibility with your existing valvetrain.
- EFI vs. carbureted: EFI engines may need ECU tuning to maximize cam gains; carbureted/non-EFI builds generally have fewer electronic constraints but require fuel supply alignment.
- Idle quality and driveability: A high-lift/long-duration cam can roughen idle. Prepare for a potential idle grind and consider stall and gearing adjustments to improve driveability.
- Installation considerations: Some cams are designed for simple bolt-on installs, while others need head work, upgraded springs, or additional valvetrain support. Review the lift, duration, and LSA (lobe separation angle) to avoid interferences.
- Warranty and support: Choose brands with solid warranties and documented installation guidance to protect your investment during break-in and tuning.
Frequently Asked Questions
- What is a hydraulic roller cam?
A hydraulic roller cam uses roller lifters to reduce friction and a hydraulic lifter system to self-adjust lash, improving reliability and reducing maintenance compared with solid lifters. - Why choose a 210/220 vs a 236/242 cam?
A 210/220 profile is typically better for broad street use with strong low-to-mid range torque, while 236/242 offers more top-end power at higher RPMs but may require higher gearing and a stiffer stall. - Do I need a tune after installing a cam?
Yes, especially for EFI engines or when changing cam duration significantly. ECU calibration or a custom tune helps the engine adapt to altered airflow and fueling demands. - Is a cam kit with lifters better than a retail cam alone?
A kit with compatible lifters provides matched valvetrain components, which can improve reliability and timing accuracy during break-in and operation. - Can these cams be used on daily drivers?
Many hydraulic roller cams are designed for street use, offering a blend of performance and drivability. Check the specific RPM range and idle characteristics to ensure it fits your daily driving needs.
