Hello again everyone! Just wanted to check in after all the recent repairs with a new and exciting issue! Haha well kind of new. So the 460 engine in my 1988 ford E350 motorhome is running pretty...

A couple of things here. I don't think that 210 is too concerning for a 1988 460 in an RV, climbing hills. It's an old technology motor, a heavy rig, and class C doghouses tend to hold the heat in. My last RV was a 26' Jamboree class C, 1988 with the 460 as well. I didn't have a "numerical" gauge, but I would regularly run at least 3/4+ on the gauge while running in the heat under load. Also, I wouldn't go too crazy with heat wrapping things; it can do more harm than good by holding the heat in rather than allowing it to dissipate.
BTW, you did alot of work on rebuilding this engine, but didn't replace the water pump, thermostat, or fan clutch? For the cost, and the ease with the engine out, the water pump would have been a cheap/easy bit of insurance at that time. Now, it's alot more work to change that unit out. Yup, been there, done that; the water pump on that beast covers pretty much the entire front of the motor!
Also, although it's a different rig and drivetrain, on my '04 class A Workhorse 8.1, the fan clutch doesn't even kick in till about 208-210, and then drops back out when the temps go down to 204. So again, I'm not sure that 210 under a load is time to panic.
