What is considered a big cam?
It is listed in degrees of crankshaft rotation.
When someone refers to a “big cam,” they mean it has longer duration, not higher Lift.
Duration at 0.050″ is the degrees of crankshaft rotation between when the lifter is raised 0.050″ and when it is 0.050″ from its resting position..
Is a ghost cam tune bad for engine?
There’s nothing wrong with a ghost cam tune, plenty of people running it with no problems. Unless you’re auto, then it’s probably not a good idea due to the effect it has on drivability.
What makes a cam lopey?
Re: What makes a camshaft Lobe Separation is the main contributing factor to the lope. The tighter the separation (lower numerically) the more it will lope.
Does a cam increase horsepower?
Performance cams increase the duration and timing of the valve openings during the engine stroke, increasing horsepower and making your car accelerate more quickly. You’ll idle slightly rougher with a performance cam, but get a throaty rumble that’s desirable for some gearheads, depending on your vehicle.
What happens if cam timing is off?
If the engine timing of the cam is off, your car will either be running rough or not at all. If the ignition timing is the problem, it isn’t as easy to notice because it has four cycles: Intake valve sucks in air while fuel is delivered by the injectors. The fuel mixture is reduced.
How do I know what camshaft to buy?
The rpm range is the range where the engine performs best. When selecting a camshaft, choose one with an rpm range that matches the other components of your vehicle and its intended use. Follow this link for more about Basic Operating RPM Range.
What is a ghost cam tune?

How do you get a lopey idle?
How do you get a lopey idle?Overlap causes misfires at idle and that makes the lope or choppy idle. … Also Know, how does LSA affect idle? … A compression leak may come from a cylinder head gasket and cause the engine to lope sometimes. … The impacts of the valves on the seats make noise.
How does cam timing affect performance?
Higher engine speed causes greater exhaust-gas velocity, which relates to greater momentum of the exiting exhaust gases. This is why a longer-duration camshaft produces power higher in the rpm range. It also causes the loss of low rpm power and economy that larger cams experience.
Does a cam increase compression?
Overlap causes a “scavenging effect” as the engine RPM increases. This is why performance cams “come alive” at higher RPMs. It’s not “just” the cam making the power, it’s the cam’s scavenging effect working as the RPM increases which increases cylinder pressure (dynamic or effective compression).
What cam should I put in my 350?

How does LSA affect idle?
A wide LSA reduces valve overlap, softens the idle and improves overall drivability–especially on the street where performance engines benefit from 112 to 114 LSA. … Nitrous engines, which make plenty of power and torque, often run wide lobe separation angles to moderate cylinder pressures and temperatures.
What is considered a mild cam?
A mild cam is usually a little bigger than the stock cam. Most of the “Mild” cams have just a bit of lope to them and will give you a bit more power than the stocker. My car, unfortunately, has a mild cam in it with it’s TR224. Still makes more power than stock but idles and rides real close to stock.
