Were all the 2 barrell carb setups called "Super Six"?

Were there any that were 2 barrel but not called the "Super Six"?

I found a 2 carb intake and exhaust manifold in a 78 truck that I am thinking of getting. No carb and the air cleaner had something on the top buts it's been ruined beyon recognition. So the only eveidence is the 2 holes in the manifold. It has the round counterweight and it's still attached to the motor. Somewhat rusty but in pretty nice shape.

I have another yard that has the carb and all, but I was thinking of buying a new or reman for about 150, if I could get the manifolds cheap.

Would you guys recommend I get the carb and all. or just the manifold off the truck? The truck also has the linkage or at least parts of it.

Thanks

I've seen two barrels that didn't have the "Super Six" label; on a Volare and a D-150. I don't know if that's because the labels were missing / removed.

Whether labeled or not, they're all the same. There were two carbs used; a Carter BBD and a Holley 2-bbl (2280/6280 ?). Seems the Carter was more common. They're more or less interchangeable.

As to your other question, it depends on the source of the carb. With what I've seen lately, every reman carb I've bought needed work. You could get the junk yard carb (provided it's in decent shape) and rebuild it yourself and save some money. If you know you've got a good source for the carb -- someone who's gonna do a good job rebuilding it -- then I might consider it.

well first find out if it's a holley and if it is leave it with them, from all Ive read it isnt worth your time and money. The BBS is apparently far more reliable.

Id snag all other parts though, from the head right to the gas pedal because you cannot adapt your 1BBL linkage to fit the 2BBL carb.

I found a reman Carter in a local shop for $170 and a new one for $360, which doesn't seem to bad compared to internet prices. I like Carter carbs. The BBD is a slightly bigger CFM as well (280 vs 250, although some books say 300). I'll check the yard this weekend. I didn't know what to look for when I was there last time.

One other question: The 2 barrel apparently came about around '77. Now the guy in my local shop told me he has a New BBD on his shelf that has the "lean burn" port. What is that and with my '74 Scamp, can I just plug it or not use it somehow? Apparently it gets activated or adjusted from a computer. Can I just not hook it up?

Thanks.

Lean burn port??!!!??? Someone want to field this? I don't think there is a dedicated port for "leanburn".

I think what the guy at the local shop was trying to say is that it is for leanburn applications, meaning it is jetted much leaner than a normal carb. I would go for a BBD over a Holley, mainly because I personally had a few problems running the Holley....mixture was waaaay too lean causing pinging and no power no matter what the timing or gas octane was. Anyway, go for a non leanburn BBD, which would be up until 80 or so on the cars and up to 83 on the trucks. After that even the BBD's were jetted very lean.

The Super Six is by far the most common two barrel manifold you'll find in a junkyard. There is a Mopar Peformance M1 cast aluminum two barrel manifold - you're not likely to find one in junkyards, but it's easily recognizable because there were no factory cast aluminum two barrel manifolds. I've heard of an export two barrel slant six which I don't know anything about, and it's possible someone may have built a do-it-yourself Super Six out of a one barrel manifold with some welding and a milling machine. But you're most likely looking at a Super Six.

I did a search on this forum and found several references to the "lean burn" BBD. Apparently at some point there was such a carb with a computer which would activate the lean burn solenoid as a fuel economy thang. Must have been on early '80's Dodge trucks or cars but maybe not on the slant six. I'm stretching here. Anyway, yes I would prefer the real deal with no lean burn crap, but, if it's the only NOS carb of the ilk that I can find.... then my question still holds.

Can I use the Carter BBD "Lean Burn" variety with a non-"Lean Burn" engine such as my beloved Scamp 1974?

I hope I didn't offend the know it all's.

A carburetor used for lean burn applications will not have ported vacuum for your distributer vacuum advance. All advance was done by the lean burn computer.

aahhh, but here we be mistaken, the leanburn computer still gets its information threw vaccum, there's a ported vac line that runs from the carb to the comptuer instead of the carb to the dist :)

main diff between leanburn and non leanburn carbs, is (SOME) lean-burn carbs had a heck of alot of wires/solinoids comming from them ;) there is no such thing as a "lean-burn port". the ONLY thing the lean-burn computer did was mess with timing and if you had the carb with all the solinoids/etc on it, it did idle/high idle but nothing to do with fuel mixture, remember its not FI we're talkin bout here ;) The main diff between the Holley is ecomomy, if you romp on a bbd, boy that gas guage moves, but if you set the mixture right, and taker easy, it'll be ok on gas, the Holley was the economy, no-power-over-onebarrel-carb. it plain sucked, ran lean (my slant had snow white plugs no matter what). all in all, they're both ok, just depends on what your doing.

Mine is a 2 barrel, but there are no SuperSix stickers on it, Its a "Spanish" slant 6.
Check the pictures:

Carter/ anything you don't recognize is LPG stuff:

This slant came out of an Barreiros Dodge 3700. You won't find them in the US, unless someone imported one, you can still buy Dodge 3700's every once in a while,..

(Here's what they look like:

Not quite true... Yes, the lean burn get's it's vacuum signal from the carb; but, it's not (at least not on my holley 1945) a "ported vacuum" port. The port is fed straight off the bottom of the carb (manifold vacuum).

For a vacuum advance to work properly, the carb has to have a "ported vacuum" port -- a slot just above the closed throttle plate, similar to but different from the idle transfer slot.

Another possibility is that he's talking about an EFC carb. It's got the mixture control solenoid (motor). You can't use this one.

You really need a non-EFC, non-lean burn carb.

Thanks Mat, for the correction. I didn't know about the MP cast aluminum manifold.

that would be a first for me to actually see one run off straight manifold vaccum, the computer gets its info just like a regular vac advance does, every Lean-burn system i've worked on (probably close to 40) have always had ported vaccum. even my 87 had a ported vac source on my Holley 1945 (emog version)....

odd.....

I had been wondering the same thing as my truck says 225-2 on the drivers side wheel well but nowhere does it say supper-six. It is the Carter carb.

One of the first applications for automotive 2 bbl slant sixes was built in Australia at 1967-69. Those engines had "Hi Performance 225" sticker in their wide but very low air cleaner housing. I have one such a thing in my 1966 Dart engine compartment. The low shape leaves incredible 0.4" space between hood and air cleaner. Matched pair, but not good idea to leave tools over the air cleaner when dropping the hood down...

I like the Hi Perfomance 225 is the original name for this improved slant, because it is published 10 years before Super Six.

US manuals does not regocnize those versions. So there is no part number for the correct type filter element for this application, too. I have found 1963-65 Corvette 327 non FI element to be perfect alternative (11.4"*2").

I'm the original and only owner of my '82 D150 Miser BBD A833/OD, with a build date of May 1982, bought from dealer here in Florida. It came with an '82 BBD that was replaced with an 83 BBD. Neither one had any electrical connections besides the choke pulloff heater, not even an idle stop switch. It also came with an aluminum manifold, altho I dunno if it is cast alum, but by the rough finish, I would say it is.

BTW, beyond the vacuum port to the ESC, and an engine temp sensor (disconnected by a TSB for 82-3 Misers), the only sensors going into the ESC are from the dual pickup coils. According to my factory service manual, there were a lot of other gizmos that could have been there, but they weren't. Even my EGR is run by vacuum.
