Blueprinting has nothing to do with balancing, it's part of the mock-up and assembly process.

A balance job will start at around $200 and can easily go past $400-500 if a lot of heavy metal needs to be added. The last Scat forged 351C rotating assembly that I did required 6 pieces of heavy metal, even with an I-beam rod and a Diamond piston. That added a huge amount to the balancing bill...
That sort of cost sounds reasonable to me.
Doesn't blueprinting involve selecting components, or adjusting components (as was seen in that You-Tube video, where the conrods were being ground) so that they are the same weight?
