From a purely pragmatic standpoint......

A SCAT 9000 series 4” crank is less than $400.
For that price I get an additional 40 cubes, a crank that is easily internally balanced, which gets me away from needing a weighted flexplate/converter and 360 specific damper.
As a bonus, I don’t have to pay $150-200 to get a stock crank cleaned, magged, and ground.

IMO, it’s a no brainer.
