Kinda cheated and started with excel spreadsheet of 100 - 999... I mean the starter did say "provide your own start data".

How did I miss this one-liner?

First, without Alteryx:
The question (in the workflow) states that 3^3 + 7^3 + 0^3 = 370...
Therefore:
3^3 + 7^3 + 0^3 +1 = 370 + 1, and since one is its own cube, and the zero is meaningless:
3^3 + 7^3 + 1^3 = 371
So... the other number we're looking for is 371.
But.. to clarify using Alteryx:
Generate rows n = 100 to n <= 999
Then filter:

n == pow(ToNumber(substring(ToString(n),0,1)),3) +
pow(ToNumber(substring(ToString(n),1,1)),3) +
pow(ToNumber(substring(ToString(n),2,1)),3)
