I'm no engine builder but I did stay at a Holiday Inn once.
Seriously though I did watch a TV show where they were showing how a block could be poured with some type of resin
to beef up the outer walls. The resin was said to be highly conductive so as to not hurt the cooling. Does any body out there
have any experience with it. Or perhaps a better memory than me. Might be an option worth exploring
