ok well i put a new trans in my car and in the process i notice the silver metal tubes that run behind the block for emissions was cut and not connected, so there for i removed them and the black tubes, now its running badly and i dont know what to do....it might not be that thats makin it run bad, i gotta check the timing but how do i put it all back together or how can i keep it unconnected and have no weird sounds and no problems? also what should my timing be set at? its a 350 tpi with cam, headwork, and headers and other little stuff?

 

You need to make sure you plug up the holes. Dont leave them open. If you remove EGR, plug the holes. When I bought my 89 someone had done the same thing. The tubes you're talking about that goto the CAT were cut, but they welded the end closed in effect plugging the hole. Now that the motor is out, I'm completely removing EGR and making it look good.

 

what is the EGR and how do i remove it? is the EGR the black box above the passenger side valve cover?, the headers have the emissions tubes so the holes u mean to plug are the ones on the top of those tubes right?
