    Default EGR install on 84 GMC 350

    Hey all. Getting back to my old project 84 GMC. Its time to put the EGR valve on and I am looking at the Edelbrock intake I got and the port is just wide open into the lower area of the intake. It kinda seems like if I put on an EGR or not its just going to breathe right past it into the main part of the intake. Am I missing something here???
    I am going back to carb from TPI and dont have my original carb parts anymore to remind me how it was setup before!

    Welcome to the Gm truck club Chevelle. If you ordered the Edelbrock manifold for the same year as what the egr valve used to fit, then it will work.

    They make a plate you can put over the egr hole but if it runs off a computer i would put an egr on it because it has to do with the map sensor and fuel reburn.
