I just got my 2.0 heads back from Len (Hoffmann automotive) and they are beautiful. It'll be weeks before I am ready for them but photos will be forthcoming.
In the meantime, I muse about valves...since fuel injectors can be precisely controlled in timing and range of movement, with stronger electronics of course, could not intake and exhaust valves be moved electrically thereby allowing variable timing and maybe even reach. Yes modern cars have variable cams but wouldn't electrical valves be infinitely varible? Surely engineers have considered this. Enlighten me if any of you know. Thanks. |

Theoretically possible if you can get a solenoid powerful enough to open under combustion. The harder part is controlling the speed at which it opens. Then the solenoid needs to operate like a stepper motor.
You should invent it!, But I bet Cadillac already has something in the works... |
