Hot or Not?

Hot or Not?
I am tempted to go buy a new gauge and mount under dash somewhere because I do not know if my 442 is running on the hot side or not.
Cruising anywhere between 50-60mph stays around the location shown in the picture. If I stop at a red light or in traffic it tends to move to the right 1 more mark..3/4 mark. Once I start moving again it drops down to what is shown in the picture.
The Rally Pac was checked out by Bob's speedometer about 18mo ago. He only told me that the oil pressure would read slightly higher than actual.
Do you think this is ok? Oh yea..'67 400ci w/ TH400. Car does have a/c, but not in use.
Thanks,
Jeff

Looks and sounds normal for summer temps. I would get a mechanical gauge and hook it up just to see what its actually running to be on the safe side. If your stock gauge is not pegged then its probably ok.

Thanks for the response Eric. I was pretty sure it was going to be ok, but I am still getting used to it since it is not an everyday driver. Thought I would ask anyway for reassurance.

Also, on the 400ci engine, do you now of another port I could connect the mechanical gauge to w/o having to remove the current sending unit? I am looking at one from Advance Auto.

Maybe get one of these, use mine for many things. I have the laser targeting one.

I don't drive the car often and still haven't purchased a mechanical gauge to confirm. By chance do you or maybe anyone else reading this post know the ~deg of each tic mark on the factory gauge?
Off hand no, but your owners manual should state what they are. Based on your pic like I said earlier you should be fine.

If your using the stock manifold, no. What I would do is temporarily remove the factory sender and hook up the mechanical gauge and note temps for your piece of mind.

I think the water port in the intake manifold is much larger than the 1/8" threaded part of that fitting (intake may be 1/2" but not sure?), and the temp probe for the gauge looks to be about as long as the entire fitting length.

I believe correct thread is 1/2-14 NPT... Plenty of styles available to choose from:

Makes sense, I didn't think about the sensor being affected by the lack of flowing coolant... The adapter you showed is definitely a good means to get the multi temp readings due to lack of intake ports...

I bought one of these inline adapters and a temperature gauge from Amazon. Works very well. Here is the adapter as bought (for $12.95) and then installed in the upper radiator hose.
