I found a original dual carb intake setup from a 66 I believe. Would this fit my 78 slant?
I have a older head, older than the original, where would I find the numbers and how do I tell what year it was made and if it will fit mine?
Thanks!

There is no multiple-carburetor intake from the factory. But all intake manifolds fit all slant six heads as the production manifold-to-head pattern never changed.

Really? I thought there were a few that came out on the chargers?

Offenhauser made the dual carb intake at least as far back as 1961, so in theory they were readily available since then.

My father had a 70 or 71 Duster that he bought new off of the lot with a 2bbl BBS. Must have been a dealer install. Traded it in for a CordobaCharger that he regretted buying after I was born (Mom needed an automatic).

Here is a link with a mag article of the Offy manifold from 1961:

No, he probably didn't; there's nothing such as a 2bbl BBS. The "S" stands for "Single", as in 1bbl. And unless he was outside North America, he didn't buy a new '70 or '71 car with a Slant-6 and a 2bbl carburetor of any make or model new from the dealer.

Too many people who were born on third base actually believe they've hit a triple.

Any Charger destined for the US market had one 1 bbl. Some export stuff had a 2 bbl available. All the multi-carb intakes are aftermarket.

I meant BBD, and typed BBS. Really meant to say Carter. Wouldn't say my father has a bad memory for those sorts of things. Could a dealer not add on a 2bbl just like they add A/C or an auto in place of a manual? Don't think he would have forgotten installing it himself but of course could be wrong.

He only had it till 75, when I had a Duster in the 90's first thing he said I should do was get a 2bbl as his ran so much better than my 1bbl seemed to.

The only 2 bbl manifold in 1971 would have been an export or marine piece. They aren't even in the parts catalogs for US market passenger vehicles. You don't just get to bolt on a 2 bbl manifold and carburetor as the throttle cable and bracket has to change. And since that wasn't an option where do you get the bracketry? If it's an automatic you also have to sort out the throttle pressure linkage to the trans which is not trivial.

If you go looking for unicorns what you'll find are fairy tails.

None of us does, but the human memory is not the camcorder it feels like. We all remember stuff—very clearly—that never actually happened. Including me; just the other day I went looking for a post I made a couple years ago on FABO. I remembered enough unique keywords for a good search, I remembered some of the other posts in the thread, I remembered exactly what kind of car was being worked on. No matter how I searched, I couldn't find it. Eventually I did find it…here on this board, not on FABO. With other posts totally different than I remembered. And a different kind of car. Yes, I'm sure it was the post I was looking for, but I misremembered (very clearly!) all the details except the unique keywords of the post itself. This 2bbl Slant-6 '70 or '71 Duster is like that, too.
It's not 100% impossible…only about 99.5% impossible. Chrysler would not have released the export-only parts to a US dealership, because installing them would've been a violation of Federal laws which were being policed rather strictly at that time. Both the dealership and Chrysler Corp would have stood to get in very deep and expensive doo-doo about it, and the amount of money a customer would have had to pay to make the gamble worth that risk would have been way higher than anyone was going to spend at a dealer on an upgrade to a Slant-6 Duster.

OR,

The dealership would have had to know enough to procure an intake and carb from Chrysler Marine, then putz around adapting them to passenger car service (fabricate throttle linkage, fabricate kickdown linkage if it was an automatic, do something about an air cleaner and a choke, etc), and the amount of money a customer would have had to pay to make it worth the dealer's time to occupy a service bay that long would have been way higher than anyone was going to spend at a dealer on an upgrade to a Slant-6 Duster.

And that's before we get into questions of the new-vehicle warranty.
You'd have to work very hard, and probably creatively, to find a legitimate, confirmable report of any Chrysler dealer in the history of ever that put an automatic transmission in place of a manual in a customer's new or nearly-new car.
So 45 years ago. I'm filing this along with all those comments I used to get at gas stations and in parking lots and at car shows: "Wow, my uncle/dad/grandpa/boss had one of these! This is a '62 Lancer? His was a '63 Lancer, he bought it new with the twin carbs and the 4-on-the-floor. Great car, but it wasn't as fast as my brother's '66 Valiant 9-passenger station wagon with the 426 Hemi. Chrysler wouldn't sell it to him until he signed a warranty waiver; I remember it like it was yesterday."

And we don't even have to get into those kinds of "memories"—look at all the articles about the Slant-6 over the years that swore up and down there was a 240 (or 242, or 252, or 7-main-bearing) Slant-6 in trucks, that there was a Hemi Slant-6 in Australia, etc.

Sorry, dude, it's a beautiful dream, but your dad's factory-or-dealer 2bbl Slant-6 '70 or '71 Duster almost certainly didn't actually exist that way.
