COMP Cams 31-432-8 Magnum 220/220 For Ford 221-302
This hydraulic roller cam targets street performance with a mild idle and strong power above 3500 RPM. Best for daily drivers and moderate street machines that want improved mid-range torque without harsh idle. Suitable for Ford engines in the 221–302 range with a 110-degree lobe separation angle and 0.512″ lift on both intake and exhaust.
Best for: street-driven Ford 302 builds seeking noticeable top-end power without excessive idle. Limitations: may require compatible springs and hardware for durability in higher RPM environments.
COMP Cams K35-773-8 Xtreme Energy 254/260 For Ford 351W
This cam is aimed at Pro Street setups with higher compression and forced-induction-ready layouts. It offers a broad 3,200–7,200 RPM range and substantial lift (0.621″/0.627″), with a 110-degree LSA. Best for Ford 351W builds that prioritize high RPM power and strong mid-to-top-end torque, provided you have supporting drivetrain, intake, and exhaust.
Best for: high-rpm street and race-oriented 351W builds. Choose this if you have upgraded heads, intake, exhaust, and a capable converter; avoid if you want a smoother idle or lower compression engines.
COMP Cams 35-826-9 Oval Track 263/268 For Ford 351W
Designed for short-track performance, this cam suits engines running in the 6,000–8,500 RPM window. It provides stable valve timing and compatibility with solid roller setups. Best for Ford 351W builds where upper-RPM horsepower and track stability are the priority. Limitations include the need for robust valvetrain components to manage high RPM stresses.
Best for: race-oriented 351W builds that stay at high RPMs. Choose this if you race a small-block Ford on tracks with strict rev ranges; avoid if you primarily drive on streets with lower RPM targets.
Comp 31-242-3 Xtreme Energy Kit For Ford 302
This kit blends a hydraulic flat tappet cam with lifters and timing components designed to maximize airflow and upper-RPM performance. The 268/280 duration with 0.509″/0.512″ lift and a 110° LSA targets Ford small-blocks from 1969–1991. It provides a balanced upgrade path for engines that already see higher RPM operation.
Best for: 302 builds that want a complete kit with reliable lifters and timing. A caution: verify compatibility with your specific valve-train parts and return springs for optimal results.
COMP Cams Sportsman Solid Roller Lifters Kit For Ford 289-351W
This lifter set features a high-strength body and skirted wheel design for stability and reduced weight. It uses pinned axles for retained durability and has captured link bars to support high-load valvetrain conditions. Best for sportsman and professional racing as well as high-end street machines that demand robust lifter performance.
Best for: high-stress racing or street cars that require durable solid roller lifters. Limitation: lifter kits must be matched to the cam profile and cylinder head setup for reliable operation.
Buying Guide: Key Purchase Considerations
- RPM targets: Align cam duration and lift with your engine’s target RPM range for best power delivery.
- Car build compatibility: Check lobe separation angles and lifter types to ensure fit with your valvetrain and heads.
- Street vs. race intent: Street-oriented cams prioritize drivability; race-oriented cams emphasize top-end power.
- Compression and gearing: Higher compression and torque converters pair well with higher-duration cams for high RPM performance.
- Supporting hardware: Upgrades to springs, pushrods, lifters, and intake/exhaust may be necessary for aggressive cams.
- Installation considerations: Some cams require additional timing covers, bearings, or lifter buckets; plan for compatibility.
FAQ
- What is a solid roller cam in an SBF engine?
A solid roller cam uses a solid lifter profile to maintain precise valve timing at high RPMs, often requiring robust valvetrain components.
- Which cam is best for street use?
Cam 31-432-8 Magnum 220/220 is described as best for street machines with a mild idle and strong 3500 RPM+ power.
- Do these cams require upgraded springs?
High-rpm or high-lift cams typically require upgraded valve springs and compatible pushrods and retainers.
- Can I run a high-lift cam on a stock engine?
High-lift cams generally demand improved valve-train components and may require compression upgrades for safe operation.
- What RPM range should I target for a Pro Street build?
Pro Street cams like 254/260 typically favor mid-to-upper RPM ranges (roughly 3,200–7,200), with appropriate supporting hardware.
- Is a lifter kit necessary with a solid roller cam?
A specialized lifter kit is often included or recommended for solid roller setups to ensure stability and durability.
