Max,
Personally, I would think about hooking that head up to a single cylinder Listeroid engine.
Here is a link to what DanB did with his.
http://www.otherpower.com/fuking.htmlYou will probably have to figure out how to put a bearing and pulley on the motor end of the shaft
after you separate it from the dead engine.
If you run it at 600 rpm with a 3 to 1 pulley ratio that will turn the head at 1800 rpm.
Right where it needs to be.
