Intake Manifold?

[BuffaloSchom]

Recently acquired a 1975 with newly built 400 engine.

My question is, what is supposed to occupy this position on the Edelbrock intake manifold?

Is that supposed to have a block-off plate for the EGR?

Thank you,

That's the information I'm getting.

Maybe choke, or I've been told EGR.

The truth is, if I knew the Edelbrock model, it'd be easier, but the research takes time.

It looks a lot like it should be just blocked.

I appreciate the reply.

That had a coil-like tubing that went into the manifold.

It was hollow tubing that passed through the metal plate, looped around, and came back out the other side of the plate and connected to the carburetor chock.

You don’t need it with the carburetor you are using. Just get a plate and two screws with the proper threats pattern.

Put the plate over it and secure it down.

This will keep dirt and debris from getting in there.

You don’t have to cover it, but it looks better covered.

I grew up working on carbs and rebuilding distributors.

Good luck.
