The issue would be clock speed/multiplier supported, I think...

A careful review of the Sun System Handbook would be best - you'd have to look at the setting in the U60 to support the 360 MHz CPU and see if there is some similar setting available in the E450.

I tend to trust the system handbook, but sometimes similar parts with different part numbers will work, despite what the handbook says, due I suspect to the last time the book was updated and the parts currently available (i.e. a version of the SM71 CPU that was released after the last update of the handbook wouldn't be listed, but since other SM71 CPUs are supported, it would be a safe assumption...
