That also only applies to Grand Prixs. The first gen W Regal got the 3800 Series I (Series II in 96)

Also, 3100s are VERY easy engines to make sound flipping awesome. Before I put the cherry bombs on, I had one rusted out stocker and one good stocker... sounded nice and low the way it was. I would have liked to keep it that way, but we have emissions inspection here.
