Posting your email addy on a public forum is a good way to be found by spambots that spend all day looking for that very thing.

I suggest you edit your email addy to: myaddy AT something DOT com.

Screatta... Do you have the car? Some of the years had the vacuum diagram posted on the radiator support cover.

Hopefully that helps until someone can post a diagram. Afterall, posting will make it available for future searching.

No I do not have the car. The engine is in my 89 reatta, it needed a bit more power

We need to know exactly what car the donor engine came from. There are differences in fuel connections and vacuum connections even within the L67 communities.

Best I can do. It'* a 94 Bonneville L67. Click on the picture for a larger one.

the donor was a 94' park ave ultra. Thanks for the picture. It was verry helpful. just one question. What is the lower portion of the bypass valve connected to?

Are you running the Buick PCM? If not, the valve won't do anything.

If you are, leave the bottom port open. It'* a vent. It used to have a small foam filter on it.

Keep in mind, the Buick didn't ever have a boost gauge, so it wouldn't have a MAP sensor like the engine pictured. That'* one difference vacuum routing that you'll encounter.
