1962 Temp sensor question
I have just put a early 80's 350 cu inch engine in my 62 corvette with stock dash gauges. I am having problems with the temp reading being too high with the 350 temp sensor (located on driver side) below exhaust manifold. It will run at 210 all day long. I think it is a mismatch to the gauge. What temp sensor should I use to match the gauge? I do not have an original one.

1962 temp sensor problem
I did use an IR gun and I find 180 right at where the thermostat is - 160 at the radiator. It gets warmer to 190 at the back of the engine but I would expect that. That's why I don't think it actually overheating. The original stock gauge read just fine with the last motor I had in there but unfortunately I sold that motor with the temp sensor in it - never thought of keeping it till it was too late. I'd like to find out a suitable substitute for it. Since the car NOM I really don't need an authentic one - after market replacement would be OK.

Head water temperature will usually be 20 degrees gotten than at the intake. My buddy had a nova with a temp gage in both for some reason (he bought the car and it must have has a dozen autometers in it, odd..) but I do recall 185 at the intake and 205 on the head when putting a new motor in it.
Can you relocate the sensor to the intake?

Most of the temp sensors available today are not calibrated correctly for the C-1 gauge. I finally contacted Mary Jo and bought a used original sensor and my gauge now works perfectly. If I recall correctly the original sensors have a dimple on the bottom.
