I am considering removing the smog pump and all associated parts and hoses on my 1985 F150 with 351W H.O. Engine. There is just too much stuff clogging the engine bay. First, how difficult of a project is this? Is it a simple removal or do I need to alter how some things are ran or what? Second, is there anything I should be aware of as far as anticipated complications? Third, are there any performance changes, good or bad? I currently do not have a belt running to the smog pump anyway.

"...What you need to do is plug resistors in TAB and TAD solenoids, remove the vacuum lines, then all the air injection plumbing and valves can be removed and the heads plugged. The EGR is a seperate system from the Thermactor and the computer treats it very differently, it also helps increase milage and power so it's a good idea to keep it anyway. If you have the DPFE system there is no way to bypass it without the computer knowing and throwing a code so you may as well keep it intact. you'll get codes if you remove the solenoids, the easiest way to avoid this is to just leave them plugged in. The TAB and TAD you could fake out pretty easy, but even the old EGR system can't be faked because the computer both commands valve movement and watches for feedback to confirm it happened, so a dummy resistor won't cut it. by Paul

Just to make sure, would this be the same for a carbureted engine? I don't think there is a computer in my truck.

Yo,
I should have asked if it was carbed or efi!
I am wavering on what to do with the egr... here is best info I have, but it is not exact, depending on carburetor or intake changes made by previous owners;

Some owners have issues with engine running too lean, vacuum leaks, etc.
