Anyone have a diagram of all the vacuum lines i can delete, EGR Valve Delete ect. Its a 20R with Stock carb. Im having issues with the engine.

Pick up a Weber carb, that'll eliminate quite a few off the bat. Then pick up an EGR delete from LC Engineering. Somebody who has done this will chime in I'm sure.

Like rowdy said grab a weber and you'll never look back. Right now all I have is one vacuum line to the dist and the big boy to my brakes. Thats it and it looks nice and clean.

For the EGR you need 2 blockoff plates as i remember. One on the intake manifold beside the carb and the crossover on back of the head. You dont need to buy them from LC just look around a swap yard. My 83 22r had all the EGR blocked from factory and they bolt right onto my 20r... maybe just a canadian thing tho

EGR has been deleted (by previous owner) (silly me sorry). I have all these vacuum lines that are open. Do i just cap them off?

Yeah cap em off or plug at base. You only need vacuum advance for dizzy and brakes like mentioned. I think LC has a diagram on site even.

There isnt a diagram on the site. I capped all the vacuums but my truck is still running like SH%#. Ill look into the weber thanks. It is the Weber 38 Im looking for right>

Hi, new here. Looking for an EGR diagram for my 20r. It appears to be gone from this post...or I'm blind. Is there any chance you could repost? Or better yet, if anyone has the FSM for 1980 pickup.?

Thanks.
