Tom,

        I maybe way off, and reply if so, but the whole flow rate being
faster, better?>  The coolant doesn't magically cool down when it hits the
radiator.  There is the chance of the coolant not staying in the rad long
enough to cool.  That is why there are restrictor plates.  This may also be
true when trying to cool the block.  If the coolant passes through too fast,
then it won't properly cool the block.
