I was wondering why most cars with cambelts have such a critical relationship between the valves and pistons given the carnage that ensues if the belt brakes, I know some engines dont have
the possibility of the valves and pistons colliding so it can obviously be done, is it that is isnt normally a consideration if the belt is changed to the intervals or is it an engine design, packaging or compression thing, i.e. is a non interference engine a bit taller, lower compression or something ?
