Almost time for the machinist!

Incorrect, the refurbished crankshaft was factory balanced with a certain set of rods and pistons. You're charging all that so it requires balancing. Factory balance was also not the as precise as it will be done by a competent machinist. 65'

I was under the impression that with the refurbished cranks the balance didn't change because it's a factory crank that has just had the journals cut and polished?

That makes sence but what if I get .030 over pistons (what I want) and it takes .040 to get the walls corrected? Then I gotta buy more pistons lol.

Building a 360 using speed pro h116cp pistons I'm gonna start a engine build thread soon I was kinda waiting till I get closer to final assembly. .030 is my goal because of the piston weight.
