360 running hot…very hot

As long as it stops creeping up, its acceptable.
In hot weather it will stabilize 10 or even 20 degrees higher.
If the pressure exceeds the cap rating, temperature will creep again.

So IMHO this will get you by for now but a factory 18" fan, matching shroud, and radiator ought to be in the long term plan.
If you want to get a clutch drive unit to save a little hp, thats an option.
You can't get a true factory, or replica radiator with the later water pump. It will need to be a combination 68-9 with a 70 up outlet position. That's what I finally did, but there are other solutions.
As far as electric goes, I discourage that with the factory wiring.
