Just read an article about a VARAC member who collects and shows some Model
T Ford racers - point was made that Model T's didn't have water pumps - they
heated the water, which pushed it's way out the top of the engine, into the
top of the Radiator, fell as it cooled, and was pulled or gravity fed back
into the bottom of the engine. So water goes HOT - T0P!
Measuring temps - I have always measured at the cylinder head, which makes
sense if you want to know the hottest temp your water gets to. But what
about oil? do you measure the oil temp as it exits the engine (ie. hottest)
or as it enters the engine (ie. as it's about to do it's work in the
bearings)? I seem to recall a Smokey Yunick article that said measure it as
it enters the block, but I've spoken to racers whose opinion I value that
said the opposite. I think that I'd rather know the temp as it goes into
the engine from the tank...
Any ideas?
