The SBC RV cam kit landscape combines performance with daily drivability. This guide highlights five camshaft kits that target small-block Chevy (SBC) builds focused on RV and towing use—combining torque, broad power bands, and smooth idle. Each option below is evaluated on lift, duration, and suitability for common RV duty cycles. The selections aim to balance street manners with enhanced low- and mid-range torque for towing or heavy loads.

Edelbrock 2102 Performer-Plus Camshaft Kit
The Edelbrock 2102 Performer-Plus kit is designed to upgrade a SBC with a hydraulic lifter setup and a balanced exhaust/intake duration. With 214 degrees of exhaust and 204 degrees of intake duration at .050 inch lift, this kit targets broader RPM range while preserving idle quality. It suits engines used for towing or daily driving where a simple, reliable upgrade is desired without heavy bump in required supporting parts.
Elgin CL-1787PK Performance Cam/Lifter Kit
The Elgin CL-1787PK kit emphasizes a practical upgrade path with a modest package weight and advertised duration of 260/260. While the listing is concise, it implies a reliable performance gain suitable for everyday SBC builds where a balanced power curve is desired for towing and highway cruising. The US-origin claim aligns with quality control expectations for reliability and consistency.
COMP Cams 12-602-4 Big Mutha’ Thumpr
The Big Mutha’ Thumpr from COMP Cams features a notable advertised duration of 243/257 and lift around .500/.486 inch, delivering a distinct lope and stronger mid-range torque. With a careful 107 Lobe Separation and a need for upgraded valve springs, this kit suits a racer-turned-RV build where a louder idle and improved pulling power are prioritized over peak horsepower alone. It’s best paired with compatible supporting components for reliability.
E1840P Sloppy Mechanics Stage 2 Camshaft Kit
This Stage 2 kit is a comprehensive upgrade for 1999-2013 Chevy/GMC LS Gen 3/4 engines, including cam, lifters, trays, pushrods, gaskets, and more. Engineered for LS-series builds, it specifies a hydraulic roller cam with a broad RPM range (2200–5400). The detailed specifications include lift figures around .585 inches and a 112-degree lobe separation, which translates to stronger mid-range torque. The package-friendly design is aimed at simplifying installation and ensuring reliability when powering larger RV setups.
BTR Truck Norris Camshaft Kit
The BTR Truck Norris camshaft kit targets Gen 3/4 GM LS truck engines with a 212/22X lift profile and a 107 LSA. This kit emphasizes a stronger mid-to-low end powerband, intended for towing and heavy payload scenarios common in RV use. The kit’s design aims to deliver noticeable throttle response improvements while maintaining drivability with stock torque converters in typical towing applications. It’s well-suited for owners seeking a robust, street-friendly torque upgrade.
Buying Guide
When selecting an SBC RV cam kit, consider the following factors to ensure the best match for your vehicle and goals:
- Horsepower vs. torque balance: RV use benefits from stronger low-to-mid-range torque for towing and hill climbing. Look for cams with lower to mid-range duration and modest lifts to preserve idle quality and stall behavior.
- Cam-to-valve train compatibility: Verify lifter type (hydraulic vs. flat tappet), valve springs, pushrods, and rocker geometry compatibility. Some kits explicitly include lifters and accessories to simplify installation.
- RPM range and driving scenario: For highway cruising and road trips, target a curve that maintains low-end torque (2000–4000 RPM range). Aggressive cams with high RPM ceilings may reduce daily drivability.
- Engine type and generation: Gen 1 SBCs differ from Gen 3/4 LS-based engines. Ensure the kit matches the engine family (small block Chevy vs. LS-based V8s) and includes appropriate gaskets or timing components if needed.
- Sound and idle: Some cams create a louder idle or more noticeable lope. If quiet operation is desired, prioritize smoother, milder profiles and shorter duration.
- Supporting hardware and tuning: Consider whether the kit requires upgraded valve springs, timing chains, or an ECU reflash. In some cases, carbureted setups may not require extensive tuning beyond basic adjustments.
- Reliability and sourcing: US-made/assembled components often provide consistent quality control. Review warranty terms and customer feedback to gauge long-term performance.
- Installation and compatibility with torque converters: Especially for tow vehicles, the transmission’s stall speed can influence overall driveability. A cam with aggressive timing may feel jerky if paired with too low a stall.
- Maintenance considerations: Aftermarket cam kits may alter oil consumption and wear patterns. Ensure you have a plan for regular oil changes and valve-train inspection during early mileage.
All five options provide distinct advantages for SBC RV builds, from simple bolt-in upgrades to more involved LS-based kits. Prospective buyers should align the chosen kit with their engine family, towing load, and daily driving expectations to maximize reliability and on-road performance.
