Hello, mine is in the rebuild process part of which I have to replace the harmnonic balancer which was dammaged when it fell off. With 550hp at the wheels will the stock HB suffice or is it better to go with an aftermarket one. I know there are a few options out there but I would like to hear what folks have done. I do have a new stock one but am on the fence whether to actually use it. Thanks again for any input.
