Camshaft Part and Phase Numbers
Each camshaft has a Part No and a Phase No.
The Part Number designates the make and model of the inlet camshaft, the duration period of the inlet camshaft/the valve lift of the inlet camshaft, and whether the camshaft profile is hydraulic.
So if we look at the Ford 1300/1600 CVH RS Turbo XR3i XR2 Camshaft Data Sheet, we see the following:-
FORC/206/420/H PH2
FORC - Specifies the make and engine type
260 - Specifies the duration
420 - Specifies the lift on the inlet valve
H - Specifies that the camshaft is designed for hydraulic cam followers
PH2 - Specifies the type of use the camshaft is recommended for
Info on Camshaft Material
Camshaft Material, i.e., what the camshaft is made from, is the most important detail in stopping premature wear of performance camshafts.
