Operating temps, now Buick V6 liniage

[Ken Kelly]

I'm lost on this thread. The Y-Job was a 1938 Buick show car. Actually one of
the first Show cars. It definitely preceded the 215 CI Buick/Olds aluminum V8.

	The LeSabre was a 51 buick show car with an Aluminum V8 engine, but it was a
supercharged Hemihead engine, again not the Buick 215 from 63.
