The stock gauge shows just right of centre when the SW gauge registers 160C.
For oil I decided to replace the stock sender unit. The stock gauge was registering around 5 PSI, whereas the new SW unit shows some 40PSI. I don't like looking at a dead gauge, but I didn't have a lot of faith in the stock sender technology. Having said that, there is an oil boss in the block just to the side of the stock oil sender that I think could be used so both gauges can be run.

Thanks for the reply! That's what I thought. I'm 100% certain that I don't any ports on my passenger side head. If I get really curious, I'll try to identify what year it was made. Believe I've seen water temp senders that tap into radiator hoses; might think about that.
Pretty sure that oil boss is intended for the optional oil filter. I have that one too. I may add an oil filter but suppose there's a tee fitting available enabling both the filter and an extra sender.
I'm with you; don't like looking at a dead gauge and have questionable faith in the stock sender. Recall sitting a stop light and watching my oil pressure go to -0-. That was a real pucker moment. I revved the engine a couple of times and drove away from the stop light and the indication returned to normal. Never found anything wrong and it never happened again.
