    That is the correct temp Luke.
    The older thermostats were 87c, now they are 92c

    Hotter engines are more efficient
    Colder engines are more powerful

    Exactly this.

    Hotter temps also reduce emissions and your heater works better in winter.
    Seem to recall the 129 is an 82 degree one.

    What temperature rating was the old one? It should be stamped on it.

    Not sure I'll have to look . Although his went on autodata and says
    Thermostat (primary/secondary) open

    An 87/88 would be my thought for a car of that age.

    Unlikely but I'd personally prefer the correct one.

    Normal running temp is 85-92'C. Fan cut in temp is 97'c and overheat is 100'c. This applies to all engines.

    92 will be fine, my 270 had a 92 degree one and it was fine including runs in mid summer around mountains without it over heating
