Buyer’s Guide: 3 Key Factors to Consider
Engine Use
Think about how you use your truck most of the time. A daily driver needs a smooth cam, while a race truck can handle a lumpy idle. Your cam choice should match your driving needs.
Supporting Parts
A bigger cam might need new valve springs or a better carburetor. Make sure your budget includes any other parts you will need. Sometimes the install cost is more than the cam itself.
Installation Skill
Swapping a cam is a big job that takes mechanical skill. If you have never done one, you might want to hire a pro. A bad install can ruin your new cam and your engine.
Frequently Asked Questions
Q1: Will a new cam make my truck faster?
A1: A performance cam can add good power, especially in the mid-range. But it works best with other upgrades like a better exhaust and intake. Do not expect a huge change from the cam alone.
Q2: Do I need a tune after installing a new cam?
A2: For a mild cam like the COMP Cams, you might get by without one. But a custom tune will always give you the best results and power. It is a good idea for any cam swap.
Q3: How hard is it to install a camshaft?
A3: It is a big job that needs time and some skill. You have to pull the radiator and front accessories to get to the timing cover. If you are not sure, get a pro to do it.
Q4: What is the difference between hydraulic and solid cams?
A4: Hydraulic cams are self-adjusting and quieter, which is great for street use. Solid cams need regular adjustment but can rev higher for racing. Most people choose hydraulic for a street truck.
Q5: Can I use a stock cam for a performance build?
A5: The stock cam is very mild and meant for fuel economy. For any real power gain, you will need an aftermarket cam. The stock one holds back even a built engine.
Final Verdict: Which One Should You Buy?
For a nice power boost on the street, the COMP Cams 66-237-4 High Energy Cam is the best pick. If you just need a reliable replacement for your stock engine, go with the Genuine Ford Parts Cam. Your choice depends on whether you want more power or just want to keep things simple.
