EGR carb base plate

Hello, I have a question. Will it do any harm to the engine if you just eliminate the EGR base plate under the carb? I have a 79' F-100....Thanks!!

It won't hurt your engine to take it off. Not sure if your state has inspections for this though. Also have to check and make sure your linkage for the carb, trans. kick down is ok if you remove it and go lower. Might be a better idea to remove it and put a regular spacer in the same size. I think with the carb sitting higher the fuel has more time to atomize. Not sure about that though. Removing this will not help your truck run better unless there is problem with it. Had a couple of these, especially if it's aluminum, rot out on some of my vehicles.

The original 'factory installed' EGR/carb spacer plates were aluminum. Heat caused them to burn up and/or MELT internally. Carbon build-up was typical problem.

The FoMoCo Service Part Replacement EGR/carb spacer plates were cast iron.

You should not eliminate the EGR system. There is a lot of information on this forum about why you shouldn't; use the search function to pull up past threads.

I do remember buying one from the Ford dealership that was cast iron instead of aluminum. Think I still have it.

If you remove it you would need to get a expansion plug to plug the exhaust hole that is down in the manifold. There are more than a few different factory egr spacers and the way they shape them, some aftermarket spacers won't cover up the hole. You should tear the dizzy apart and make sure the advance is set in the short slot too.
