Thermostat
Did Oldsmobile use Robertshaw thermostats on the 1966 400? I don't know if this is a stupid question but I had a 65 442 with a 455 that needed a Robertshaw thermostat to cool properly, since it had such a large opening for the coolant flow because of the poor water pump design and was just wondering if the 66 400 used the same thermostat to cool properly.
