Why a Good RV Cam for 350 TBI Is Necessary

From my experience working with 350 TBI engines, having a good RV cam is absolutely essential. The 350 TBI is designed for efficiency and reliability, but without the right camshaft, it can’t reach its full potential. A quality RV cam helps optimize valve timing specifically for the throttle body injection system, which improves power delivery and throttle response. I noticed my engine ran smoother and had better low-end torque once I upgraded to a proper cam.

Additionally, the RV cam is built to handle the unique demands of a recreational vehicle engine, which often runs under heavy loads and varying conditions. My engine’s durability increased because the cam profile reduces unnecessary stress on components while still boosting performance. In short, a good RV cam balances power, efficiency, and longevity — all things I value highly in my 350 TBI setup.

My Buying Guides on Good Rv Cam For 350 Tbi

When I first started looking for a good camshaft for my 350 TBI engine, I realized there’s quite a bit to consider to get the right balance of performance, reliability, and value. Over time, I’ve learned what features and specs matter most, so I’m sharing my insights to help you make a confident choice.

Understanding the 350 TBI Engine

Before diving into cam options, I made sure to understand the basics of the 350 TBI (Throttle Body Injection) engine. It’s a popular small-block Chevy engine known for its simplicity and reliability, but it benefits greatly from a camshaft that matches its fuel delivery system and intended use. Whether you’re looking for improved torque, horsepower, or just a smoother idle, the cam has to complement the TBI setup.

Types of Camshafts Suitable for 350 TBI

I found that camshafts for the 350 TBI generally fall into three categories:

  • Mild/Stock replacement cams: These are ideal if you want to maintain daily drivability and fuel economy without sacrificing reliability. They offer moderate lift and duration.
  • Performance cams: If you want noticeable gains in horsepower and torque, especially for towing or RV use, a performance cam with higher lift and longer duration is better.
  • High-performance/Competition cams: These cams are usually overkill for RVs but great if you’re into racing or extreme modifications.

For my RV, I leaned towards a mild to moderate performance cam to keep my engine responsive and smooth without compromising street manners.

Key Specifications to Look For

When choosing a cam, these specs were crucial for me:

  • Duration: This affects how long the valves stay open. For a 350 TBI, I aimed for a duration between 210° to 220° at 0.050” lift to balance power and drivability.
  • Lift: Higher lift can increase airflow and power. I chose cams with about 0.450” to 0.480” lift.
  • Lobe Separation Angle (LSA): A wider LSA (110°-112°) generally gives a smoother idle and better vacuum, which is important for TBI engines.
  • Cam Profile: Hydraulic roller cams tend to be quieter and more efficient, but hydraulic flat tappet cams are more budget-friendly.

Compatibility and Installation Considerations

One thing I made sure was that the camshaft I picked matched my engine’s components — especially the valve springs, lifters, and timing set. The 350 TBI uses specific lifters, so I checked whether the cam was compatible or if I’d need to upgrade parts. Also, I considered professional installation because proper timing and break-in are essential for cam longevity.

Brand Recommendations From My Experience

I found certain brands consistently deliver quality cams for the 350 TBI:

  • Comp Cams: Their hydraulic roller and flat tappet cams offer good performance options with solid warranty support.
  • Crane Cams: Known for their reliable hydraulic flat tappet cams that are budget-friendly and street-friendly.
  • Edelbrock: They provide cams tuned for mild performance improvements, great for RV daily drivers.
  • Texas Speed & Performance: If you want a more aggressive cam for increased torque and horsepower, their offerings are worth a look.

Additional Tips I Learned Along the Way

  • Always check if your current valve springs can handle the cam’s lift; weak springs can cause valve float.
  • Consider upgrading your timing chain and gears if you’re installing a higher-performance cam.
  • Don’t forget that the cam affects your engine’s vacuum; if you use vacuum accessories (like brakes or HVAC controls), choose a cam that maintains good vacuum levels.
  • Break in the cam properly after installation to ensure long life.

Final Thoughts

Choosing a good cam for the 350 TBI engine isn’t just about picking the biggest numbers. It’s about matching the cam to how you use your RV and maintaining drivability and reliability. For my setup, a mild to moderate performance hydraulic flat tappet cam from a reputable brand gave me the perfect blend of power and smooth operation. I hope my guide helps you find the right camshaft that fits your needs and keeps your RV running strong!
