What does an intake cam do?
In piston engines, the camshaft is used to operate the intake and exhaust valves. The camshaft consists of a cylindrical rod running the length of the cylinder bank with a number of cams (discs with protruding cam lobes) along its length, one for each valve.
What does Degreeing a camshaft mean?
The term “Degreeing In Your Camshaft” means you are making sure the camshaft’s position in the engine coincides with that of the crankshaft, so that their rotation is synchronized. A few degrees of misalignment can affect the engine’s operation dramatically.
Is Degreeing a cam necessary?
Pit Stop with Marlan Davis: Degreeing a custom cam ensures its maximum performance, helps prevent piston-to-valve contact, and protects against assembly error. The bigger the cam, the more important this is.
Which is the best camshaft for low torque?
COMMENT: GOOD LOW END TORQUE AND PULLING POWER. PERFORMANCE CAMSHAFTS Street or strip, Engine Pro Performance Camshafts simply out perform the competition. Our manufacturing accuracy promotes improved valve train stability resulting in improved power gain.
What is the torque of a mc2199 camshaft?

Can a Ford E303 performance camshaft work in 1985?
A: The Ford Performance E303 Performance Camshaft will not work in a 1985 as this cam is designed for a hydraulic roller cam motor, and only 1985+ motors are roller cam motors. Helpful ( 3) Thanks for your input! Q: What is the CARB OE number for this cam?
Which is the best camshaft for 327 C I?

How is intake duration determined in a camshaft?
The first two events determine the intake duration (closing minus opening), which is built into the camshaft. The exhaust opening and closing are the next most important parameters. The exhaust lobe is fixed relative to the intake lobe by the lobe separation angle.
What should the cam lobe separation be on a V8?
To picture cam lobe separation a little better, look at the end of a traditional V8 camshaft. Draw a line through the center of the cam out through the point of maximum lift on each cam lobe on a pair of lobes. You’ll usually find the measurement between 104 and 115 degrees.
What does 108 degree separation on cam shaft mean?
Separation refers to the spacing between the intake lobe and exhaust lobe on the cam shaft. This spacing (or separation) is expressed in degrees on the cam, not on the crankshaft. So, a 108 lobe separation means the intake and exhaust lobes are 108 degrees apart from each other on the cam shaft. This spec by itself really doesn’t mean anything.
What do you need to know about cam specs?
When it comes to performance parts, understanding cam specs and their affects will help you select the best cam for your specific engine. The four important camshaft specs to understand are duration, centerline, separation and lift. DURATION Duration refers to how long a valve is opened in relation to crankshaft rotation.
