Trey- Unfortunately, I did not do that because I was unaware it needed to be done. The engine had an SFI external balance flexplate on it when I bought it (he ran an auto trans). I called PRW, told them my setup, verified their flywheel would work with the McCleod clutch I was getting and ordered the flywheel. They did not mention any balancing was required.
Here is the flywheel I ordered.

Since the specs matched what I needed, I thought it was good to go out of the box. I sold the flexplate the engine came with. I guess I can try to get in touch with the buyer and see if I can get it back.
Thanks for the input,
Daniel
