Smitty says:  I did that one time with a 70s aircleaner snorkle with the
vaccum valve on it to select heat and it worked very well.  I moved the
temp sensor down under the oil cooler to switch the valve. The Ned Nicols
69 Monza that was in the museum for a while was modified with a 4bbl by
GM engineers.  It had a metal box loosely fitted to the bottom of the
4bbl plenium under the carb.  It was fed with heat from  one of the
manifold covers down below by a 1/2" tube.  I saw no indication  it was
valved to shut the heat off when warm.
