At CAT CAMS, we have the technology to grind camshafts with inclined cam lobes thanks to our CNC grinding machine that can set movement of the complete grinding wheel assembly at the same angle as the lifter movement. This is required for engines with valves pointing towards the center of the combustion chamber. A top notch example is the Ferrari 333 SP engine, featuring 5 valves per cylinder (see image). The outside intake valves having an angle of 3° to the center. The 2 exhaust valves have an included angle of 8° to eachother.

Later production engines, such as the F355 and F360, enjoy the same technology and can benefit from CAT CAMS upgrades for camshafts and related valvetrain components as well.
