Well, I was thinking that if the bypass were close to the thermostat (and sensors) it would be a moot point or maybe actually get the true engine temp to the sensor sooner. As it is, the temp sensor works off the coolant that is trapped in the thermostat housing. Except for the small bleed hole on the thermostat, the housing is a dead end for coolant flow until the thermostat opens. The temp sensor actually lags behind the actual temp during warm-up. If I had that housing I'd want to see if I could drill and tap for a bypass spigot. At the same time I'd like to see if a different thermostat would fit (what Spud mentioned).
