What is considered a mild cam?
An RV or towing camshaft, which is considered a mild performance or an economy cam, will often have a narrower LSA, between 112 and 114 degrees. Hot street camshafts usually have 110- to 112-degree LSA, while high performance and racing camshafts will often run between 105 and 108 degrees.
How much horsepower does a cam add to a 350?
Replacing the 2G with a Q-Jet and intake alone can be worth 25-30 hp. Toss in a mild cam and cylinder head upgrade and the power gains really start to add up.
What makes a cam sound lumpy?
what makes the cam have that lumpy sound? The overlap of the exhaust valve closing and intake valve opening causes the engine to be inefficient at low speed which results in the lumpy idle. The closer the Lobe Seperation Angle the more the overlap, the more duration the more (typically) the overlap.
Does a cam make a car faster?
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.
How much HP can Vortec heads make?
GM Vortec cylinder heads are used with a Comp Cams Xtreme Energy 262° camshaft to produce 390 HP and 426 ft-lbs of torque. These numbers are made with 87 octane, while most of the combos on my site used 92 or 93 octane gasoline.

How do you know if your car has a cam?
post a vid of the exhaust, we will be able to tell if it has a cam or not. If the thing pulls hard past 5k rpms, like doesnt run out of steam, then it probably has a cam.
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.
What is a good camshaft duration?
Performance cams typically have durations ranging from 220 up to 280 degrees or more. The longer the duration, the rougher the idle and the higher the cam’s power range on the rpm scale. A cam with a duration of 240 degrees of higher will typically produce the most power from 3,500 to 7,000 rpm.
What do the cam numbers mean?
The first two numbers are the degrees of opening being 210 for the intake and 218 degrees for the exhaust given normally at .050 inch of lift. The next two numbers are the valve lift of intake and exhaust in thousands of an inch. The final number is the degrees of overlap.
Can you put a cam in a stock engine?
Registered. You can’t swap just the cam and nothing else. Not counting the fact that sticking in a big cam in a stock engine and it running worse due to a mismatch with cylinder head and intake airflow, at the very least you MUST swap the springs.
What gives a cam a lopey idle?
Overlap causes misfires at idle and that makes the lope or choppy idle. It causes a lot of intake reversion which causes the engine to basically choke on it’s own exhaust during idle. The more the overlap the more the lope will be.
What is a Stage 3 cam?
The LS1 Stage 3 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.
How much lift can Vortec heads handle?
The factory Vortec heads use a light, single-wire valvespring with a damper that generates between 70 and 80 pounds of load on the seat. Because these heads are meant to work with a 1.5:1 rocker, their tall valve guides can only handle maximum valve lifts of around 0.420 inch.
