Shim under bucket

Some cage manufacturers have been offering camshaftless implementations for years. Intake and exhaust are completely controlled by solenoid management. Firmware design and hardware robustness must be top-shelf to be reliable. In return, total customization of the timing with infinite variableness, less weight, as well as a lower mechanical profile engine top end. I suspect implementation is not perfect since we'd see more deployment in vehicle production.
