Were Buick 350s ever equipped with a AIR/smog pump? A friend of mine wants to swap a Buick 350 into his '84 G-body, but with the new arrival of emissions tests in our area, the car would need to be equipped with the following - AIR pump EGR valve PCV valve Charcoal Canister/Purge system Catalytic Converter The emissions test is strictly visual, just checking for the presence of these items, not whether or not they actually work. For example, the same friend has a '79 blazer/383 that has been equipped with aftermarket fuel injection without EGR. He RTV'ed an EGR valve to the intake manifold, ran the hose down behind the motor, and it passed emissions with flying colors. If anyone can shed some light on this AIR pump issue it would be greatly appreciated. Thanks!
Scott, I think the california 350's had everything starting in 71 or 72. PCV, Trans controlled spark advance, EGR, and A.I.R. The non California cars in 72 didn't have either EGR, or A.I.R.
Be careful about swapping engines into a 1984 car. Here in VA, the inspector types the vin into their state-supplied computer system, and a diagram of the engine and all its required smog items comes up on the screen. No if, and, or buts - everything pictured must be there or you fail. If PA uses the same company to supply those computers, you can forget many engine swaps.
PA has several ways that allow some good ole hot rodding. The under 5K a year exemption, and Collectable and Classic registrations. Its always a safe bet to hook up your emissions stuff for appearance, but try not to fret to much yet.
