I checked these radiator references from Taylor books
on the internal combustion engine at UCLA and these
are the ones I found most interesting. At 36 cents a page
I passed on printing them from the microfiche.

There is a place where you can buy them however and hopefully
they are better quality than you can get out of printed
microfiche.

8.84 is in English and has little on rads themselves.
Good reference on duct design however.

8.82 has no rad data either.
