Only california emision lb7's had a egr, if you have one there will be a long round tube running from the back side of the passanger head to the front of the engine, the back of the tube will be connected to the exhaust up pipe and the other end will have the valve and the conection to the intake pipe where the intercooler plumbing conects to the engine! i wish i had a pic for ya but i myself have never seen a lb7 with a egr, ive only heard about them!!!

This isn't the best picture. I'll try to get something better later. I describe it as looking similar to a tall boy beer can on its side. It's on the passenger side, near the firewall. This pic is from my LB7.
