Correct EGR for duraspark conversion
Have been doing research on your website for a eec-3 to duraspark ignition conversion. I have a complete parts list together. Do I need a different egr? My truck is an 84 150 300 6 w/ a 4speed.

yeah one of those
Thanks buddy, as usual this site has come in handy more than once. Used to the older fords 79 and down. This is my first in the 80's and the junk they put on these engines is crazy. I do have a selenoid vacume line going to the egr so i will buy an earlier one. Just want to simplify this engine while maintaining the emissions systems. Will post pics of my change over----------More to come and again thanks Jim

I had the same questions when I did my conversion. The EGR part numbers are the same. The only difference is that in your truck, the egr is electronically controlled. In the DS-2 equipped vehicles, the egr is vacuum controlled. I changed my truck over to the vacuum controlled egr, and it passes emissions with flying colors.
To change over to the vacuum controlled system, you need to get the vacuum diagram of a DS-2 vehicle. On the water pump heater hose nozzle, you should have a valve with two wires going from it to a cluster that may be attached to the rear part of the valve cover. I have a 300-6, that how it was on mine. That valve on the water pump needs to be changed to a vacuum controlled 'ported vacuum switch'. On my engine, it has nipples for 4 vacuum ports. I got my information off of a 1983 F100 w/ the 300-6. Maybe, someone out there, or a Ford Dealer has a vacuum diagram of a 1983 or older engine that matches your application. Good luck.

Cool
Thanks Paul still doing some research on this issue-- I'm going to buy the factory service manuals for the 84 and the 1980. I am currently buying parts for the 1980 follewed by the service manuals for the 80 as well. These manuals are great, you can take a truck down to the frame with these things. Between that and this website maybe I can keep the pain down to a mininmum.--Thanks for everything--Jim

Jims84, I just noticed that you are in Phoenix, AZ. One option to get around emissions in the Phoenix area, is to register your truck as a 'collectible vehicle'. Your truck is over 25 years old, and is eligible for collector status. The only drawback, is that a collectible vehicle has a mileage limitation of I think, 2,500 miles per year. This is different than the "historical vehicle" registration, which still requires emissions testing on vehicle years after 1966. I have been mulling this over myself, as I'd like to dump the one barrel setup and go with the 4 barrel Holley, Offy intake, and the fuel injection exhaust manifolds.
