Cam lift is a term used in relation to engine technology such as camshaft profiles. Cam lift is the amount of lift the camshaft provides to the valves in the engine; this lift is measured in either inches or millimeters. Cam lift is a crucial part of engine tuning, as it affects how much air and fuel is drawn into the engine. Increasing cam lift can result in more power, but too much cam lift can cause engine damage.

Cam lift is determined by the shape and design of the camshaft lobes. The lobe itself is the raised portion of the camshaft that pushes against the valve springs and opens the valves. Different lobe designs result in different amounts of cam lift, depending on the size and shape of the lobe. To increase cam lift, flat-faced or high-performance cam lobes are used, which are designed to open the valves further and provide more lift.

The amount of cam lift also affects valve timing. If the camshaft profile is designed with too much lift, the valves will open at the wrong time, which can cause a misfire or even engine damage. If the camshaft profile has too little lift, the valves won't open as far, resulting in a loss of power. Finding the right balance of cam lift and valve timing is essential for getting the most out of an engine.

In conclusion, cam lift is a vital part of engine tuning and design. It affects how much air and fuel is drawn into the engine and also affects valve timing. It is important to find the right balance of cam lift and valve timing in order to get the best performance out of an engine.
