What is a camshaft and what does it do?
A camshaft is a rotating object— usually made of metal— that contains pointed cams, which converts rotational motion to reciprocal motion. Camshafts are used in internal combustion engines (to operate the intake and exhaust valves), mechanically controlled ignition systems and early electric motor speed controllers.
Which methods are used to provide drive to the camshaft?
In most engines, a camshaft is driven by the crankshaft by a pulley and belt, by a gear-drive chain, or by direct gear-to-gear drive.
Are timing belts wet or dry?
From what I can tell the timing belt is a ‘dry’ setup, like most other timing belts and the oil pump is not driven by a belt, but by the front of the crank.
What do you need to know about cams?
What you need to know about Cams. #1 – the most common camshaft error made by people is to OVER cam the engine. There are a number of things, which affect the cam’s performance………… Cylinder head flow rates: The cylinder heads must be able to flow enough air for the time that the valves are open.
How much valve lift does a cam Hughes Engine have?
Using a 1.5:1 rocker ratio this equals .075″ valve lift. Any duration less than this has no effect on power. Understanding the duration at 0.050″ may seem confusing but the important thing that must be remembered is: as the duration at 0.050″ gets larger the camshaft gets larger and vise versa.

How are intake and exhaust pipes related to CAMS?
Intake: The intake must also flow enough air to support the cam and cylinder fill. Exhaust pipes: The exhaust pipe must not only flow enough, they must be designed so that the reversion pulse is compatible with camshaft timing. There is a little clue here for you sharpies and that is the word AIRFLOW.
How to choose the right camshaft for your engine?
Choosing a particular type of camshaft for an engine build is an important decision that has to be made before any other parts are ordered or machined. Choosing a cam requires answering some basic questions, the most important of which is the engine application itself. Are you building an engine for everyday driving? For towing?
What’s the best cam profile for a racing engine?
If you are uncertain as to which cam profile best suits your needs, please contact our technical support staff at 619-661-6477. Level 5 camshafts are designed for fully prepared, high compression, all-out racing engines and chassis.
Using a 1.5:1 rocker ratio this equals .075″ valve lift. Any duration less than this has no effect on power. Understanding the duration at 0.050″ may seem confusing but the important thing that must be remembered is: as the duration at 0.050″ gets larger the camshaft gets larger and vise versa.
What are the characteristics of a Crower camshaft?
High vacuum, smooth idle and maximum efficiency are characteristics of these cams. Stock or small cfm carburetor, small diameter tube headers and dual exhaust are recommended for maximum benefit.
