What does putting a bigger cam do?

What is a 3/4 cam?
To fill this demand, Ed Winfield took the intake lobe from his full race cam and the exhaust lobe from his semi cam and called it a 3/4 Race cam (see Flathead Performance Cams). … Since that time, 3/4 Race has become a generic term for a high performance street cam, i.e. something less than a race cam.
What is the advantage of a roller cam?
Roller cams also allow for steeper lobes. In other words, they allow for more “area under the curve.” This means the valve opens faster and remains at a higher lift for a longer period of time. This allows for more airflow and more power. When changing cams, roller lifters can be re-used.
Can you use roller rockers with a flat tappet cam?
Roller camshafts and lifters can be used in an engine that features nonroller rockers; by the same token, roller rocker arms can be used in an engine that features a flat-tappet solid or hydraulic camshaft.
How do I know if my cam lobe is worn?
Here is how to measure cam lift.Remove tappet cover as necessary. … Select the lobe that you want to measure, ie intake for number 1 cylinder.Turn the engine where the push rod doesn’t move at all. … Turn engine, now push rod starts moving up. … Measure the distance between the two markings, thats your cam lift.
How much does it cost to put a cam in a truck?

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.

What is considered a long duration cam?
A 280-degree-duration cam holds the valves open longer than a 260-degree-duration cam. Holding the valves open longer allows more air and fuel into the engine and also allows more to get out through the exhaust. Longer duration (higher number) improves top-end power but almost always sacrifices low-end torque.
