You have 1 of two engines. You either have the 3100 V6 or the 3800 V6. The 3100 has an aluminum upper intake manifold with 3100 SFI on it. The 3800 has a plastic engine cover that says 3800 Series II. If there is no engine cover then look at the upper intake manifold. The 3800 has a black plastic intake manifold.
