Want to remove smog equipment

[Anonymous]

I just bought a 1966 Mustang with the 200 and a "cruise-o-matic" tranny. This car is very clean and all original under the hood especially. The car no longer needs to pass smog in California, what is the best way to remove the smog pump and equipment? In other words what will I have to change in order to remove all this smog stuff and what will I gain?

the best way? grab the wrenches, remove the smog parts, remove the unknown mess running here and there, remove all of it and plug any open ports.
only thing you MIGHT have to change is a fanbelt IF one belt drives teh smog pump and other accessories you need, otherwise it should run great without all that
good luck!!--josh

I did just what's described above, bought allen head bolts to plug the six air holes in the intake, then I just bought a 1978 head . . .

A 66 Mustang original shouldn't have any smog equipment, should it...?

If it's the California emissions engine, it has the Thermactor system.

sorry to steal your thread but is the same true for a fox body mustang? I'm worried about some of the vacuum lines that come off of the air pump hoses. I would love to have that mess out of my engine bay, would give me a lot more room and look heaps better.

The later models had a different system. The 66 California Stang had an air injection system that recycled some of the waste. The Calif carburetor is not involved in the smog system. The later systems had some kind of vacuum feed-back and charcoal cannister setup, so it would not be the same so you can't just pull it out.

So would it be okay to pull it all out of my 66 and plug open ports?

'78?
My Zephyr has a plastic box on the right fenderwell that has several vacuum hoses, not all were connected so I don't know what to do with it.
The YF carb I put on, doesn't have near as many vacuum connections as the 1946 carb did, especially the large bore port on top of the carb...
The only other emission item was the EGR and that has been removed.
Can I toss it? Bill

You'd have to ask someone who actually knows something about that. Sorry.

I have the emissions stuff off of mine, but still have the cannister hooked up. It vents gas from the carb and gas tank. I would actually like to get a new one, but haven't found a good deal on ebay yet :!:

Thanks JackFish, I thought it was vapor recovery of some type.
I will try to figure out how to hook it up.

Ratter27, i would just rip it off - in my experience, the plumbing toward the gas tank end is usually rusted/rotted off, leaving a mess of useless plumbing. as for the carb end, it may make the car a little cleaner" (environmentally speaking) but other than that has no benefit to you whatsoever. i would toss it (as i have on a couple rigs of my own)

My searches have led me to this topic...

I would like to be sure about whether or not I have the thermactor system on my '66 200 Mustang. What are a few sure fire ways to tell?

I see no canister hooked to the exhaust or anything weird like that. I DO have a PCV system sucking valve cover gases into the manifold.

The reason I want to be sure is some adjustments are different based on whether or not a thermactor system is present.

Thanks,
John

I am sure a restorer would be interested in the parts you take off.

The Thermactor system has a pump that could easily be mistaken for a power steering pump or messed up AC pump at the top on the driver's side of the engine opposite the real alternator. There is a brass tubing system that routes the air injection to the cylinders. I forgot where, but it is on the top of the block to the head. You can't miss it. If it has no wires or large hoses going to it, it is the Thermactor.

Thanks Ludwig.

I am thermactor-free then. Good to know since my Mustang was built in San Jose, CA.

[ludwig]

If that's your car in the sig, then you are a man with no Thermactor.

Yep! That's the ol' land shark in my avatar!
