CAMSHAFTS - THE NUMBERS GAME


Are the cams shown here the same?
YES, they are.... by the 'numbers'!

Cam Profiles

Cams A, B, C shown above all have the same lift as shown at L, and duration shown at D. Yet they are obviously very different. If Cam B is correct in design, then Cam A would give good low end but less horsepower and float the valves more easily. Cam C would give plenty of top end but would exhibit a narrow powerband and open the valves too rapidly for good reliability.

The Numbers will also vary drastically depending on the lift at which the figures are recorded. In all, it is nearly impossible to compare or evaluate cams by the 'numbers' only.
