The small diameter hub you are using has a weight of 5.12 pounds. However, the larger harmonic balancer weight is 8.60 pounds. That's a difference of 3.48 pounds between harmonic balancers.

I know of people that have replaced the harmonic balancer from the hub style to the dampener style in street applications under the premise that the Oldsmobile engine is externally balanced, and the counterweights are the same.

I assume your rotating assembly was externally balanced like the OEM, just to be sure, ask the shop that did the balancing if you can exchange the balancer since they have the same counterweight.
