Water temp in Magnum (crate motor version). Where to place probe for gauge? Temp switch for fans?

Thanks to everyone.

I found this one. One review notes that it specifically does not fit the Manifold on his Magnum 360 despite seeing that it's compatible with Mopar small blocks. Is there anything unique about Magnum engines and their manifolds that I need to look for?

The reviewer said that his manifold was an Edelbrock, fwiw.

I don't know off the top of my head, but I can snap some pics of my Magnum EFI Airgap if you need them.

Also, grab one of those hand-held laser temperature guns from Harbor Freight or EBay. They really come in handy for learning what's what as far as normal temps are on your motor.
