Well after years of dodging the rules on emissions, I have finally been snagged. The problem is not the actual emissions but instead the lack of proper equipment. The previous owner swapped a late 70's motor in place of the '87 original. I have no idea what equipment i need but I'm planning a trip to the salvage yard. I need to know what I have to take home with me while i'm there. I do not plan to have any of it actually function as intended, it just needs to be there. The cat is obvious, but beyond that? I guess I really just need a good place to go to see some microfiche, maybe some images. Did the '87 have just efi or were there some 460 that had carberation? Also, this is a biggie, will the 1987 intake fit the late 70's motor. Thanks for your help and sorry for sharing my headaches.

 

'87 was still carb'd on the 460. You'll need all the EGR equipment, smog pump, diverter valve and all associated plumbing. An '87 carb intake should fit your engine.

 

An 87 460 DID NOT have a cat, even in Cali emissions trim.
You need EGR, 2(yes, 2) A.I.R. pumps, the plumbing, exhaust manifolds and injection manifolds that screw into them. As well as a bunch of vacuum hoses, temp switches etc, check out your emissions sticker on the core support.
If you have a square bore carb on an egr equipped manifold, don't bother changing the manifold, it is the same part.
The AIR pumps on the 460 only pumped in more air to dilute the exhaust stream, no more no less, so the emissions equipment outside of the egr really didn't clean them up, it just made them look cleaner...

 

What State's emissions requirements do you need to meet, fokker?

The pumps didn't only dilute the exhaust, they injected air that allowed unburned hydrocarbons to cook off in the exhaust manifolds.

Otherwise, 82F100SWB is exactly right.
You may have to include the twin charcoal canister and a carburetor that has the bowls vented to it. (as well as all the hoses and ported vacuum diverters)

There was no EFI 460 until the 1988 model year, though some may have production dates from 1987.
The 4V carbureted intake manifold will fit 98% of 460's... with the exception of SCJ heads.
Even there, it would "fit" but the port mismatch would be awesome.

 

Check your emission regulations as some places will allow an earlier engine swap and that it's year will be the basis of the test.

 

Since these things have no OBD computers and therefore are no codes to read.

From everything I've encountered the -vehicle- has to meet the standard in place at the date of manufacture,
Mine has to be dynoed and meet those limits... as stated on the emissions compliance sticker... that is on the underside of the hood.

 

All the emissions equipment is there on my 87, if you need pictures just ask me.

There is a lot of emissions stuff, I think anyways. 2 pumps, vented float bowls, 2 carbon canisters, huge network of vacuum piping, EGR. . .lots of vacuum pots. You might be better off finding a complete motor and stripping it all and swapping it over. The most important thing for me has been the emissions sticker on the valve cover that says "NON-CATALYST". I had a fight 2 inspections ago because they failed for not having cats. It took a call to AAA or the State Police to set them straight. The inspector told me every vehicle since 1976 has a cat, lol. . .

 

Not if it is over 8,500 gvw.
If you look at your compliance sticker it will say "Heavy Duty Vehicle"
The limits are pretty liberal. I've never had a problem passing.

 

I think it's a Federal law (clean air act?) that only allows engine swaps from the same model year or newer vehicles (unless the engine was offered in said vehicle). I'm not sure which emission standard they have to pass, vehicle or engine year of manufacture.

 

Legally you can only swap in an engine of the same emissions year or newer. If you swap your engine to a newer one, they're supposed to check it's emissions based on the year of engine swapped in.

Would the inspections place actually check the year of your engine and run the test for that specific model year? In California and Massachusetts they probably would, I don't know if any other states would even bother to look at the engine that closely.

 

Oh, yes. . .I understand all that, but they didn't and I tried to explain it to them and I got that "yer fulla $%#@" look

I also had an argument with an exhaust shop about the same thing. My welder was broke and I needed some pin holes filled. . .don't even get me started on the tard who began explaining to me how wrong I was and what the fines were like

BTW, does your instrument cluster say "unleaded fuel only"? I never payed attention, but they didn't like that and didn't beleive me when i told them I swapped it out for one with a tach. . .

Ugh. . .

 

My truck came with a tach.
Yes it does say "unleaded fuel only"

 

What happened to the OP?

Maybe we scared him off?

 

LOL. . .

He is in for a task to put all the emissions stuff back on his truck. . .he will also need all the special brackets to hold everything. This could get expensive

Not sure why people insist on stripping that stuff off?

 

Most people don't like it because it "clutters up" the engine compartment, or they feel it is "robbing power"....
