The present camshaft is a simple, reliable device to control intake and exhaust valves.
Why would you want to replace a hunk of metal with more parts?
A camshaft doesn't need electric power. It works at temperatures below zero to temps well above boiling water.
My '76 911 camshafts have worked for almost thirty years without failure and could go longer.
It accurately opens all six valves on one side at rpms up to 6,500 RPM on my engine. A lot higher RPM's with better springs and lighter valve trains.
The valves work under conditions that would make hell look like a resort. High temps, over fifty cycles per second, then seal and withstand several thousand pounds of pressure and fire.
This highly developed system just doesn't get the respect it deserves.
