is it pointless to put a 180 tstat in a l67 that has a stock pulley air intake 104 autolites ? any pros or cons of a new 180 t stat?
 






pretty much. it wont affect how hot your car runs unless you can get the heat out of the radiator by turning on the fans at a lower temperature.
 
Without at least a 3.4" pulley and a PCM there is really no reason to go with 104's. The 180 T-stat will trigger a Check Engine light because you are running too cool. The upgraded PCM should be programmed to elimintate the light while running a cooler T-stat.

this is not true.........I am running a 180 t-stat and no codes......it just doesnt hardly do anything. You may run a little bit cooler on the freeway( I am curently running in the 180's with this on the motor, but it wont matter in town because it cant cool enough without the fans reprogrammed. I have never had a code from this, or heard of a code from this........Leave the stock temp one in unless you are replacing it for some reason. If you replace it you might as well save ten bucks and put in the cooler one now if you are going to eventually. It wont hurt anything........agreed on the plugs being too cold for an almost stock setup though.
