If anyone has a mid 70`s 450se, could you please give me a hand? I need a diagram of the vaccum lines routing in the engine compartment. I have a 1974 450se that runs great but won`t pass smog inspection test during idle but passes under load.

You may want to post this in the " Tech Help " section.
It would help if you could tell us the actual numbers from your e-test !
