Default LS1 Harmonic Balancer Diameter?
Does anyone know what the diameter is of the stock LS1 harmonic balancer?

I am trying to calculate blower speed and need this info. All I know is that is is around 7".

I have not measured it myself, but I asked the same question as you for the same reason, and I was told 7 1/2 inches. That is what I have been using to calculate impeller speed.
