Gary,
	I am sorry if I have caused any confusion.  Yes, the pressure due to
combustion does produce a stress on the conecting rods.  However, the
stress due to rpm on the rod I feel is higher than that of combustion.  I
have not done the actual math to prove this, just using my common sense, as
I have never seen a rod broken under normal cicumstances(i.e. lacking
SEVERE detonation) but have seen some come appart at high rpms.  
	The only thing I don't know how to interpret is how the compressive stress
affects the fatigue of the rod.  I have yet to take that class.  

Sincerly,
