1968 Dart cooling system & gauge Questions

I agree a 3 row radiator is the way to go. Especially if you live when it gets hot and the car has ac which creates even more cooling demand on the radiator since the condenser is in front of the radiator. I've read other people here state that their gauge runs in the middle usually so maybe that's where it runs on a normal 80 or 90° day. I know my other Mopars seem to run in the middle on warmer days and then on cooler days are usually more towards the left.

I would say thankfully my car doesn't have A/C, but it would be nice on those hot days! I just wish Ma Mopar would say in the owners manual that "this is the normal operating temp range on the gauge", instead of everyone guessing. I know most people would install an aftermarket gauge, but I don't want one in my car. I probably just need to not over think this, as I have had the gauge quite high (waiting in a long line to get into a car show on a 95 F + day), and the car has never lost or spit out coolant, and that was with the factory 2 core radiator.

I think my 72 dart does not exhaust the heat when not moving
I can pull over when it starts to cook, open the hood, get almost knocked over from the ball of heat,
and almost immediately the vapor-locky (brother of the jaber-wocky) goes away in under 2 minutes
I plan of somehow venting that, as is seems all my x country problems start with unmoving bumper to bumper
factory 4 blade stone stock /6, 19" no shroud
just like mom made it

If you can afford to stop, I don't disagree with that, that would definitely cool off the motor quicker.
