Temperture sensor
'78 .... engine change and smaller thread sensor has a different ohms reading than the origional so I know the gage will be wrong,
What have youse guys done to correct this? Have you been able to make one read right at various temp ranges by adding a resistor?

I took my head (aluminum) in Monday to the machine shop, had the hole drilled larger and re-tapped. Got it back Tuesday and only hurt $30 worth. Or you could go to the hardware store and buy a couple of adapters to make the original sensor work.

I have a 93 chevy truck with a 355 and sportsman II heads. I had a problem with the hole being a different size over the stock heads. I went to different auto parts and hardware stores but the only place that had what I needed was Van's auto parts. I found a coupling to make it work. I don't like it too well as it sits really close to my headers.

I used a 1/2 to 3/8 adapter from an autoparts store with the stock style sensor. 
Works fine, clears the headers easy. But I have aftermarket heads, your hole might be drilled in a different location but I doubt it. It can't hurt more than a few bucks to try.
