I haven't had it (87 F150 351 4bbl) inspected yet, but I'm gonna have to soon.Then again I have friends....And it has no air pump, or thermactor, or heat riser for that matter....might replace the heat riser but by the time I'm done with it the Holley will be gone along with the intake, and that wonderful little tube on the back of the heads. I've got nothing against the emissions equip. it just wasn't there in the first place...
