i think i like the idea of painting the block two different
colors. never thought of that. personally though, i would like
my block to be flat black, or something close, and everything
else that is producing heat to be a dark color. i also believe
that the black color can hide imperfections better under the
bonnet.
now remember, all this is just my opinion. you can agree or
disagree and it won't change my thoughts either way. also, i am
not trying to persuade anyone into changing thier personal
preferences. if "dirty harry" wants to paint his engine hot
pink, it's totally up to him.
