I'm doing away with all the emmision stuff on my 79 f1504x4 and was wondering if someone makes block plates for the egr valve and manifold? 351m.

 

Usually the plate under the carb is removed. It is usually all rusted out anyway. You will have difficulties with pinging etc if you remove the EGR. Check some of the old threads here for more information.

 

easy just use block off intake gaskets from summit.

 

Block off intake gaskets would require that he remove the entire intake manifold. If you don't run heated intake air there can be other problems in the winter time with blocking the exhaust passage. -Good old tradeoffs... So much fun when you get to re-engineer a vehicle!

 

Just pull the egr valve off and make your own block-off plate (I used a tin can on my old 302) bolt the valve back on and it all looks stock. Don't worry about the pintle on the end of the valve, you only have to block the other hole..

 

A good looking block off plate can be fabricated easily from a piece of 1/4" X 1" strap. Then you can remove the offending EGR valve and all of it's vacume equipment from your engine compartment. It sure cleans up the look of your engine but keep in mind what Torque1st said about the Pinging problem. Premium or mid grade gas will probably take care of that if it's a problem at all, and that is not really so much of a money issue anymore since premium is less than 10% more money.

If you don't get the plate out from under the carb it may still be leaking exhaust gases into the intake due to burn through.

 

Do I need to put some kind of spacer under the carb when I remove the plate? The egr is disconnected but not removed yet and It seems to run okay. Should I retard the timing a bit to keep it from pinging?

 

As I recall you need a plate to cover holes in the intake manifold flange that connect to the exhaust. Maybe something from Summit Racing thats aluminum. I would wait to see about the pinging and treat it as needed. A richer jet in the carb may help.
