Expert Buying Guide For Silverado Cams
Purchasing camshafts is a crucial decision for your vehicle engine because you need to decide that before buying other parts, it is important to build the engine. And that makes a cam different from other parts.
There are so many varieties of camshafts out there in the automobile world. But you are supposed to select your own one depending on your vehicle type and the frequencies of journeys you are going to use it for. Here is the list of necessary factors to consider before purchasing a cam attached, along with the review of the best camshaft for 4.8 Silverado.
Vehicle Type: At first, you have to shortlist the camshafts available in the market for your vehicle type. If you own a stock car or race car, you will require a different kind of camshaft from that of a truck as cams determine the engine’s horsepower and torque curves. Check if the cam is compatible with your truck engine and its requirements.
Purpose: What kind of trips are you going to enjoy with the vehicle, and what type of roads will it use? Is your vehicle lightweight or heavy? These questions are the most important ones to answer before buying cams for your engine. Lightweight vehicles usually go with bigger cams, and heavy vehicles want low-end power.
Lift And Duration: Lift is measured in inches and refers to the distance created by the rise of valves from their seat in the cylinder. Usually, there are two types of lobes – gross and lobe. Improved valve lift allows more open space in the intake and exhaust ports of the cylinder.
Duration is the time span that a cam keeps a valve off its seat and is measured in degrees. Thus the more valve area is open there to flow; your engine will make more power. Short-duration cams are good for low-speed engines, and long-duration cams are good for high revving engines.
Lobe Separation Angle: Lobe Separation Angle or LSA is basically a number showing the measurement of degrees that separate the cam’s intake and exhaust lobes’ peak lift points. If your truck is a street vehicle for everyday use, then go a good idle quality, decent vacuum for operating power brakes, and overall good power production.
Flat Tappet VS. Roller: Roller cams are made of steel and use lifters with a roller, while flat tappet cams use a lightly curved bottom to slide against the cam lobes. As a roller cam can make more midrange and top-end power than a flat tappet cam, the former one is preferred by travelers and trackers, but the latter one should be your choice if your truck stays mainly on the everyday street.
FAQs About Cams for 4.8 Silverado
What are the reasons behind the failure of a camshaft?
Answer – The most common reasons behind the failure of a camshaft are worn-out lobe, incorrect break-in procedure, distributor gear wear, different types of mechanical interference like spring coil bind, valve guide boss interference, rocker arm slot to stud performance, etc.
What are the benefits of a hydraulic lifter?
Answer – The biggest benefit of the hydraulic lifters is their ability to perform quietly without demanding much maintenance while transmitting much less shock to the valvetrain. Usually, hydraulic lifters are self-adjusting. They tend to use oil–damped, spring-loaded plunger to help maintain valve lash.
Can camshafts increase horsepower?
Answer – Camshafts can improve your vehicle engine’s horsepower because they can increase the duration and timing of the valve opening during engine strokes.
What are the signs of a faulty camshaft?
Answer – When your camshaft is failing, your engine will automatically let you know that. When you find your vehicle idling roughly and accelerating slowly, you may understand that the camshaft position sensor has begun losing its ability. Other symptoms of this are frequent stalling, drop in engine power, and reduced gas mileage.
The above-mentioned camshafts enlisted in our review of the top 5 best cams for 4.8 Silverado are some of the smartest choices your valuable engine can build with. Take care of the duration, lift, timing, etc., of your camshaft and enjoy a fine journey with your Silverado.
