Cooling
In the Cadillac V-8 water enters the right hand cylinder
block under pressure. Half of the water is by-passed
to the left hand block. Thus, the maximum distance that
cooling water must travel through the block is far less
and the variation in temperature throughout the engine
is about half of that in a straight eight engine. In straight
eights water enters the block at the front and must travel
the full length of the engine before cooling the rear cylinder.
Cooling effectiveness obviously diminishes as
water passes from front to rear of the engine. This
results in hotter running rear cylinders, causes uneven
cylinder temperatures, and, therefore, enhances the
danger of warping cylinders and valve seats which
results from unequal heating. Lubricating quality of
