EGR, A.I.R. pump and a Cat. I don't know about here, but back home, if the engine wasn't offered as an option, the Ref station wouldn't let it pass... ie, 460 swap wasn't legal, unless the vehicle is older than '75, then anything goes, as long as it at least passed the sniffer
well then, all you need is the EGR and A.I.R. pump
This is reason #3 why I prefer these 78-9s - there's practically nothing needed for smog equipment
Call your DEQ station tho, and ask about the BB swap, and see if it's legal to do for the 79. It'd sure be a shame to spend all that time, money and effort, if it won't pass smog... but then you could sell me the engine and tranny, cause I just picked up a pair of D0VE-C heads
Don't know if its the same there as here but here you can do just about anyswap as long as it passes the sniffer for the year of vechicle. My 79 has egr(blocked off), Air pump, cat(plugged) and still passes the sniffer. Just remember the the smogged 460 have the timing retarted 8* from the factory to help pass the sniffer. Mine is timed "straight up" and has a hard time passing. I have to lean it out really far to where it lopes real bad at idle then it just passes.
In Ga all you need is a set of cats. I have 2 cats on my dual exhaust with no pump no egr no canister or any other stuff from factory. I passed with flying colors. This maybe different in you state.:toothless
If only ALL the states could adopt ONE set of regulations(nad NOT california's!), with slightly more strict regs for the cities with worse emissions
Tim, I don't know what you've found out, but I pulled this from the OR DMV site -
In Portland and surrounding areas, all 1975 model year vehicles and newer must be tested. In the Medford area, all vehicles 20 years old or less must be tested. Cars, trucks, vans, motor homes and buses powered by gasoline or alternative fuels such as propane are tested. Diesel powered vehicles with manufacturer's gross weight rating of 8,500 pounds or less are tested
EGR and cat's are required on a 79 in OR, Tim. They might not catch the EGR but they WILL inspect for the cat. If you do a 460 it will need to pass the 400 emission parameters. WHatever ya do, don't tellem it's a swapped in motor! Tellem it's a 400.
Now you get to learn the biggest difference between 78's and 79's.:banghead
NC is pretty lenient. They didn't start testing cars till July this year and it's only for 96 and newer. But just in case.....I have a 78 that is non-emission and my 79 has a 429 swapped in. I swapped the fuel gauge and filler neck out of the 78 into the 79 because they only open the fuel door to make sure the restrictor hasn't been tampered with and now my fuel gauge doesn't say "Unleaded Fuel Only" on the bottom of it. My truck has so many engine mods that it would never pass anyway so at least now I can try to convince them it's an early 79 that fell through the cracks
The closest thing to "cats" I have are the ones that like to sleep on the hood and leave paw prints everywhere :toothless
guess i got it good workin at the dealership. In pa u need the works for the visual test and gotta pass the 2stage sniffer test. Swappin in the 460's gonna be easy for me cause i've tossed all the emissions junk away(didn't have cat's anyway).
Ok, first some background. So I have a 460 in my 78, behind that is a ZF5-42 & divorced NP205. Gears are 4:11, and I'm now running 37" treads.
The 460 I bought newly rebuilt from a guy in PA that said he was going to use it for a project but changed his mind. It came long block, and the heads...
I have a 78 with the original 400 and C6, and although the motor is still running I've decided to swap in a more modern drive train.
If you had the option of 4bt cummins or 5.0 Coyote or another motor which would you recommend?
I have a brand new redhead steering box on my 79 bronco. The other day I went and hauled a 65 chevy truck home on my trailer and noticed that at idle it did not want to steer. If I revved it up a little it steered like it should. Is this the pump going out?? It is not making any noise and is...
So when trying to fix the charging system it looking like there is a green with red wire that goes the the volt. Regulator in the engine bay, that wire has no power so I tested the one that comes off the ignition and it has power. A diagram said they come together in splice 401, but I cant find...
Pros and cons, need to move axel centreline 3-4” so 40’s clear mad dogs ... what did you do (whith pics if you have em,links to build would be good as well) for relocation of track bar,and other steering issues encountered. I’ve 8bolted my Dana44 whith 3/4 tone components from balljoint...
