Why a Good RV Cam for 350 TBI Is Necessary

From my experience working with a 350 TBI engine, having a good RV cam is absolutely essential. The camshaft controls the timing and duration of the engine’s valve openings, which directly impacts performance and efficiency. Without a properly matched cam, I found that the engine could feel sluggish or lack the smooth power delivery I expected from a 350 TBI setup.

A quality RV cam is designed to optimize low-end torque and provide a broad power band, which is exactly what I needed for my daily driving and towing. It helps the engine breathe better at lower RPMs, making acceleration more responsive and improving fuel economy. In my case, this meant smoother starts, better throttle response, and a noticeable boost in overall drivability.

Additionally, since 350 TBI engines are often used in trucks and RVs where reliability is key, a good cam ensures longevity and reduces the risk of engine wear caused by improper valve timing. I’ve learned that investing in the right RV cam not only enhances performance but also protects my engine, giving me peace of mind on every trip.

My Buying Guides on Good Rv Cam For 350 Tbi

When I was searching for a good RV camshaft for my 350 TBI engine, I quickly realized how important it is to choose the right one to match your engine’s setup and your driving needs. Here’s what I learned through my experience that I want to share with you to make your decision easier.

Understanding the 350 TBI Engine

Before diving into camshaft options, I made sure I understood the basics of my 350 TBI (Throttle Body Injection) engine. This engine is known for its reliability and moderate power output, but upgrading the cam can really help improve performance, torque, and throttle response. Keep in mind that TBI engines have specific fuel delivery characteristics, so the cam profile needs to complement that system.

What Does a Camshaft Do?

The camshaft controls the opening and closing of the engine’s valves. For my RV, which needs good low-end torque and smooth drivability rather than high-RPM horsepower, I focused on cams designed for torque and efficiency rather than aggressive performance cams.

Key Factors I Considered When Choosing a Cam for 350 TBI

  • Cam Profile (Duration & Lift): I looked for a cam with moderate duration and lift to improve torque without sacrificing idle quality. Too aggressive a cam can make the engine rough and reduce fuel economy.
  • Compatibility with TBI: Since the fuel injection relies on steady airflow, I avoided cams that cause the engine to run too lean or rich.
  • Idle Quality: I wanted a cam that keeps the engine running smoothly at idle, which is especially important in an RV for comfort and drivability.
  • Powerband: For my RV, having a strong low- to mid-range powerband was crucial for climbing hills and towing.
  • Brand Reputation: I trusted well-known camshaft manufacturers that offer cams specifically designed for 350 TBI engines.

Types of Camshafts That Worked for Me

  • Hydraulic Flat Tappet Camshafts: These are a great budget-friendly option and work well with stock or mildly upgraded 350 TBI engines. They offer good torque and smooth idle.
  • Hydraulic Roller Camshafts: If you want a bit more performance and longevity, these cams reduce friction and can improve throttle response while maintaining good idle.
  • Performance Camshafts for RV/Towing: Some cams are designed specifically to enhance torque and reliability for RV and towing applications. These were my top choice since they match my driving style.

Additional Tips From My Experience

  • Consult Your Mechanic: If you’re unsure, ask your trusted mechanic for recommendations that suit your RV’s weight and typical driving conditions.
  • Consider Supporting Mods: Sometimes upgrading your cam means you also need to upgrade your exhaust, intake, or ignition system for the best results.
  • Check for Camshaft Specs: Look for cams with duration around 200-215 degrees and lift around .400″ for a good balance on 350 TBI.
  • Break-In Procedures: Follow proper camshaft break-in procedures to ensure longevity and performance.

My Final Thoughts

Choosing the right camshaft for a 350 TBI engine in an RV is about balancing power, smoothness, and reliability. I found that a mild to moderate hydraulic cam designed for torque and daily drivability gave me the best results. Don’t chase extreme performance if you want your RV to be comfortable and dependable on the road. With the right cam, your 350 TBI will feel stronger, more responsive, and ready for all your adventures.
