I have spent days searching for the dimensions of the H22A and well its just not out there. Does anybody know any of the dimensions I can use to base a scale off of? Dimensions of the Valve cover would give me width and length measurements, Then maybe the diameter of the front pulley so I can get the height.

I am building a tube chassis to put it in and have to do some design CAD work before I start buying parts..

 

Come on somebody can go measure the valve covers on their H22.
