1991Blitz

I have made the recent purchase of a 1991 Camaro with a 1986 350 TPI engine swapped into it. I have what I think is a vacuum leak that is causing a high idle. Most of the hoses are missing so I would just like to know what all needs to be connected for the motor to run properly. Any other advice on what would cause the high idle would be much appreciated as well.

As a quick note, no inspection will have to be done to the car.
