Dan's right. Probably been changed. 307's are usually very gutlass and yes, because of government all these cars had smog pumps origanally. If your computer isn't doing anything then it's just there. Thats how my car is I guess.
Pics of stock engine 87 442?

I have a stock 4-4-2, with an unmodified 307. I'll try to get some pictures of it this weekend. Mine doesn't have a smog pump. Although these cars were computerized, they did very little in comparison to today's ECM equipped cars. Basically controls a solenoid in the carb, from what I know.
If you can try and see the block casting numbers. They are right in front of the intake manifold next to the oil fill tube. Also get the number that is off the heads. It should be 1 capital number and/or a letter next to it. It will be on the left corner of the head.
I would try taking a digital camera to the local junk yard and photographing a car with a 307 in it. I think a B body should be about the same, so you may want to look at the big cars too. The major difference externally is the air filter housing (dual snorkel with chrome lid). Functionally, the VIN 9 cars have a computer cut out for the A/C compressor under WOT, so some minor wiring differences probably exist. I happen to have the complete GM manual set for Oldsmobile RWD cars in 1985, but I can't figure out how to use my all in one as a scanner or I would post the diagrams.
This is what I got for you... The numbers on the block read "4790 GM 5.0L" then a number or letter I cant see follows, I will be able to get to it this weekend when I change the holley back to the original type Q-jet.
The plugs are all there for carb, (MC sol and TPS) you can see those plugs in the pics. It does have an EGR valve, no EGR switch or what ever the hose comes from for the EGR valve...
The carb used the heat tubes for choke, I remember my regal used the same type of choke. I hope the carnb I ordered has the same type or I'll be sending it back and hunting for the correct one (again).
You can also see the cruise control plug goes to nowhere and the other pics are to show the lack of any sign of a smog pump... ever...
That casting number on the block does not look like an Olds number, but it somewhat resembles an Olds engine. It also does have the holes on the heads plugged from the smog pump. As long as it has a separate oil fill tube behind the water pump and not in the valve cover it is a 307. You need to make sure that your engine has the computer controlled distributor also, not just a regular hei one. You should be able to get most of your missing parts from a regular 307 even if it was not a 442 engine. I am not sure if the carb and dist. will be setup any different on that engine. All of the emmisions stuff that was removed will be the same on any 307 so you will not have any problem their.
Yes, definitely had a smog pump. I just finished taking mine off my '88 Classic. Looks like he used the same square-head NPT plugs as I did to plug off the holes. Those two slots in the heat stove for the ThermAC air cleaner are where two more of the AIR pump tubes went. (between #3 and #5 spark plugs). In the third picture down (fuel pump) the bolt beside it with the star washer underneath it was holding the smog/AC (if it had AC) pump brackets down. They used a two-piece combo bracket to hang them. The empty groove on your pulley in the same picture suggests that an AIR pump once made its home there.
That carb doesn't look like mine for sure... Sounds like he got frustrated with the CCC system and slapped on a regular carb, and I would assume a non-ECM controlled distributor set up.
I can see the bracket for the heater hose that sits against the "heated vacuum" style choke. Same style as mine, you're on the right track there.
This is my carb# if it helps you
Rochester Quadrajet Model E4MC, Carb# 17086008
The only problem is that mine is the crappy "Y" code motor, where as yours would be the less-crappy "9" code. I would guess they might use a diff. carb?
That cruise control plug sitting there would be attached to a vacuum diaphragm. The vacuum diaphragm has a wierd bracket made from round steel bar that bolts partially to the alternator bracket.
I may be renting a shop, and after a move in I should be able to snap some pics for you of my motor. It will have the A/C and AIR pump removed, but will have cruise control installed, and i'll pop off the air cleaner for you, so you can have a decent look.
I'll also take pictures of the AIR pump and bracketry that that I removed. (if i get a chance to take pics at all....)

Sam, I can get you some pics tomorrow of my 87 442 tomorrow. It's stock for the most part. I also have the correct vacuum and wire diagrams if you need them.
I would start with going to the bone yard to get all the missing components, you will need just about everything located on the manifold.
Just about any VIN Y 86-90 Olds 307 out of a wagon or sedan would give you everything you are missing. The only thing you would have a hard time finding is a VIN9 170860009 Carb with the correct Idle Load Solenoid.
You should be fine without it though, sometimes they pop up for sale with the correct computer which might be the most difficult to find since no one keeps them.
Just a thought but you might be able to buy a VIN 9 aftermarket performance chip and install it into the VIN Y computer and get the same result. I am just not sure if the A/C cutoff is controlled within the chip or on the circuit board.

The a/c cutoff is controled by a switch on the accelerator pedal, similar to the kickdown switch for TH400's.
I have both carb and computer that I took off my '85 442 if you need either of them.

I gotta ask... what do you want for them?
I know my computer is there, I don't know if it is getting any power but here is a clue for you folks who know how they work... my MC plug for the top of the carb,... it sparked when it tapped the intake, does this mean my computer is doing something since the plug does have power or does this not really say anything about the order of the computer?
I know my dist. has no vac. adv. but does have the 4 plug. The car does one of those slug starts then runs, it idles poorly but has decent upper RPM power and response... My guess... static advance due to no computer control, set by previous owner to run fine at mid rpm for driving purposes...
Just a guess, but I was thinking about putting a vac. adv. dist (without 4 plug) down in it and seeing how it starts and idles. starting it is not cool out in public...
rr...rrr....rr...r....r..r......VRRROOOOMMMMMmmmmmmmmmmm......
