egr elimination
Well i went out today and dismanteled the egr system on my truck .
Took the carb of and the egr spacer pull ed the egr off and blocked off the ports to the egr with a peice of cardboard gasket material. removed all the other vacume lines associated with it. MAN WHAT A DIFFERANCE IN THE WAY THE MOTOR RUNS . SOOOO SMOOTH NOW . And on top of that i was able to advance the timming to almost 18 deg before it started to ping under load. It even helped the driveabilty. Man I love my truck!!!!!!!!!!The only question i have is about the bowl float vent on top of the carb If i pull this off will it affect anything i was worried about fuel spillage.
Six strings and Ford trucks music to my ears.

What is this, are you running on Fuel vapours again?

Although the bowl vent is supposed to vent vapors only its possible it could slosh a little fuel out if you went over a rough enough road or a bump and then idled the motor. It shouldn't hurt performance any to keep the carbon canister hooked up or you can just cap the bowl vent tube.
I have often wondered about the EGR like who came up with this bright idea. The hole that it blows exhaust through isn't big enough to pull a significant amount of exhaust so the amount of reburn is minimal. After a short time the port starts to clog up with carbon so then the system becomes less and less effective until its useless. A motor needs plenty of oxygen for good combustion and good combustion makes for clean emissions. How can displacing good clean air with carbon monoxide be doing any good?

Birddog, you can run a piece of hose from the vent up to the air cleaner, or, like mine, just leave it open. If you plug it, there may be drivability problems because of the pressure buildup in the float bowl.
Hottarod, I agree that the EGR is a bad system. It was designed as a cheap way to reduce the NOx emissions back in the old days. The small amount of burned gases that are re-introduced, actually cools and slows the combustion charge. This reduces emissions and allows for a leaner mixture. I had to go up 3 jet sizes when I disabled mine.

All,
I believe the EGR system is a vintage emmission system. It no longer is in practice. With stricter emission laws it is a hinderance rather than a help. Reciculating carbon monoxide never seemed practical but, by removing emmissions from the exhaust system they passed the test for a few more years.
