318 cam shaft selection/upgrade for stock engine

I'd just run stock 340 cam.

It would be "ok". The reason I stopped recommending it has been covered in the posts previous to this. No one really knows what the specs "are" for that cam. In fact, I have measured more than one and gotten something different. Quality control? Proprietary grinding? Operator error? I am FAR from perfect, but since I have friends who have had similar results, I sorta think operator error ain't it.
