    I am getting ready to replace the motor in my 84 and noticed it has a pump off some sort just under the alternator, I can only assume this is the dreaded smog pump. Dumb question but is it illegal to remove this when I reinstall the new motor?

    illegal, I do believe so. But, so is speeding. =) As long as your state doesn't inspect under the hood for emmisions equipment, who cares? So, my answer is "Smog pump, what smog pump?"

    does that pump actually do anything, or is it just another Gov. regulation?.....i.e. catalytic convertor.....

    I moved from Az to CA a while back. 86 or 87 I think. If you let me know what this thing looks like and where it is, I will go see if there is one on my k5.

    I put a new motor in my 85 and left the smog pump off. just be sure that you remove the emissions sticker uder the hood.
    We have the sniffer test here and the Blazer pased fine w/o it. I also have a bigger cam, Eld.intake, Holly carb.
    It's all about the tuning.
    good luck

    When we moved over here I was only 2 years old, so I have no idea what was done to the Blazer at that time. Sorry.

    I beleive Ca. does a vision test if they do not see the emmision compenet that they are looking for, you fail the test
    even if you tailpipe emmisions pass the sniffer test, which is an easiy task if the motor is detuned/tuned.
    Good luck

    Yes, its illegal, yes they look for it durring the visual, and yes they will fail you if its missing, then if you fail, you have to take it to one of the recommended mech.s to fix it. Plus in the metropolitan areas, LA, San Diego, and most of the state, they put the rear up on teh dyno rollers, and measure levels at two or three speeds, with the load of the drive train on it. Yes CA emmisions are a bitch, if it conforms to the CA emmisions now, keep all of it, or else you'll have to pay a huge one time fee for a non conforming vehicle. Keep everything if you're coming to CA, i spent 15 min arguing that mine never came with a cat, which it didn't, but the book said it was optional, i knew the guy so he didn't give me a hard time, but i've had friends get screwed because the guy at the gas station was an idiot.

    The air injector pump pumps compressed air into the exhaust to thin out the exhaust mixture to reduce back firing into the manifold and to reduce the amount of hydrocarbons and carbon monoxide in the exhaust.
