180 thermostat and temp gauge fix.

[mikep]

I'm running a set of world product heads. Good heads and all but he opening for the temp gauge sensor is too small for the original 1/2" NPT sensor so I had to mount it on the manifold plus since I am running a 180 degree thermostat I wasnt getting the engine into the temp range It had to be in to move the temp gauge needle past C on the gauge. I spent some time at the parts store and found a suitable replacement that fits the 3/8 NPT hole in the world product heads AND has the correct resistence value to put the needle straight up at 180 degrees.

So if you are at the parts store or junkyard looking for a temp sensor to put your needle pointing at the sky ask for a 1963-1970 VOLVO temperature sensor.
