I'm in need of some advice here. So I'm trying to get together a plan to four barrel swap my 318 2bbl in my '87 Dodge D100. Its bone stock besides headers and dual exhausts which will be going on soon. I plan on getting an Edelbrock Performer (3776) which is for EGR engines. I want to keep the egr because I know deleting it isn't going to be simple and if I attempt to delete it, it will most likely just cause problems. So with that said I'd like to put a Holley 600 cfm or 570 cfm on but I have no idea if any Holley carbs are even made with EGR compatibility. I'm a bit of a newbie and this is my first time putting a 4bbl on something and I'm pretty lost lol. If anyone here has any suggestions or recommendations for carbs that would work on a 318 with EGR, (Holley or Edelbrock it doesn't matter much) it would be much appreciated!

 

Deleting EGR doesn't cause issues with the engine performance, infack it will clear up drivability issues. If you already have headers your EGR has probably been defeated already.

 

Headers haven't been installed yet but thanks for the info, I might try to see how it runs if i go ahead and delete it then

Yeah, loose the EGR if at all possible.
Only concern is, will your stock cam be letting you have enough air flow to take advantage of the headers and 4V?
Sorry, don't know a lot about stock '87s, but the word "smog" comes to mind.

Also Save all your old parts in a box... Just incase you ever want to go back and reinstall it later...
As for deleting the egr system... Delete it all...
as for the carb... Holley 650-750cfm or a Carter/Edelbrock 650-750cfm
as for the manifold... A Dual Plain should work just fine....
