What is the purpose of a cam?
Summary of the Article
A cam in an engine plays a crucial role in enhancing performance. With a larger cam, the intake valve opens wider, allowing more fuel and air into the cylinder, resulting in increased power output. However, camming a car also has downsides, such as inefficiency at low RPMs. Adding a cam can indeed increase horsepower, especially at higher RPMs. The intensity of a cam determines its aggressiveness, with smaller intensity indicating more aggressive opening and closing. A stage 1 cam can add up to 158 horsepower to an engine. It is legal to have cammed vehicles, although some local laws may require notification to passengers if they are being recorded. Cammed cars can be daily driven, as long as they are properly tuned and not too aggressive. However, they may lower gas mileage. Camshafts can be illegal unless they come with a CARB certification number. Camming a car can make it louder, and a broken camshaft can cause severe damage to the engine. Stage 2 cams are designed to increase power while maintaining drivability and are compatible with stock components.

Does camming a car make it faster
In theory, the greater the lift and timing, the more air/fuel mixture gets to the cylinder. This is how camming your car increases its power output. However, there are downsides to running a cammed car. The most common con in camming your car is that it will be inefficient at low rpms.
Does adding a cam increase horsepower
And it can increase horsepower. Now by doing. This you may also be able to increase uh to a higher rpm. So if your engine say reps to 6000 rpm um and you've done plenty of different swaps to allow for
What makes a cam aggressive
In other words 'intensity' described how quickly the cam opened and closed from lower lift points to his standard lift point of 0.050”; the smaller the intensity, the more aggressive the opening and closing.

Does camming a truck waste more gas
Any performance cam will lower your gas mileage (period). If you are going for economy and not performance then there is no need to port the heads, since economy driving is done at low RPMs and velocities are low.
Are camshafts illegal
yes, unless it comes with a CARB certification number. Any modification is illegal (even just changing the mufflers) unless it's certified by CARB. wow, are there really any good cams that are certified

Product Description. The LS1 Stage 2 camshaft was designed for enthusiast who want to increase power while maintaining excellent drivability and manners. This cams can be used with stock torque converters, stock rear gears, stock intake manifold, stock exhaust manifolds etc.
Does a Stage 3 cam add HP
It is a lot more aggressive and worth an additional 20 hp on top of the gains from the 8710 grind or 123 hp over a stock LS3 when combined with a stroker kit.
How many miles does it take to break in a cam
First, put about 50 miles on the engine and then drain the oil and swap filters. This will get rid of the majority of the metal that ended up in the oil during break-in.
How much does it cost to cam a car

Is cam bad for the engine
A vehicle with a damaged camshaft may suffer from reduced engine performance due to cylinder misfire. Your vehicle may hesitate and lose power, jerk or shake aggressively, consume more fuel than usual, and produce more emissions.
Is straight pipe bad for your car
A straight pipe exhaust system helps your engine run more efficiently. That's because the backpressure created from the catalytic converter and muffler no longer exists. Less pressure on your engine results in more efficient operations, so you'll see a slight increase in fuel efficiency.
Is every car cammed
Cam is short for camshaft, the engine part that opens and closes the valves to let the air-fuel mixture in and out of combustion chambers. Every engine manufactured today has, if not one, then at least two or more installed.

Can you over cam an engine
"The very worst thing you can do is over-cam an engine," Consolo says. "Lift, duration, and lobe separation angle need to be matched to the true end purpose; getting any one of those wrong can over-cam the engine, which is worse than under-camming." That's from both a power and enjoyment perspective.
