I am wandering about this deal of running 200 + degrees water temp
for the most HP, it just never seemed to be that way, remember everyone
cooling their motors between rounds at the drags in the old days and just
the fact that my 327 powered roadster always pulled hardest when pretty
cool. I'm wandering is this apparent change due to the widespread use of
aluminum heads and even blocks that make the elevated temperatures better
for power?? Kvach
