Thanks Chris....I dug a little more into the Mocal external hermostat. Turns out it works just like the take-off plates:
Quote:
Cold oil enters the
thermostat and is bypassed through the center of the
unit returning to engine (figure 1). During warm-up
the thermostat never closes off oil flow to the cooler,
rather, it offers a less restrictive path for the oil to flow*
allowing the cooler to acclimate to system
temperature. As oil warms to 180 degrees (200 in high
temp versions) the operating "waxstat" closes the
bypass permitting full flow to cooler (figure 2).
*percentage of oil bypass can vary up to the point
where the bypass is closed and full flow to the cooler

Looks ike the Canton is the only full shut-off option out there (so far)
