Please note: There are some important and significant differences between the 318 BBD and the slant six BBD. See here: http://www.slantsix.org/articles/supers ... -list1.htm

More specifically, http://www.slantsix.org/articles/supers ... /page1.jpg

A 318 BBD will not give you the oprimu mperformance and the choke linkage will not work properly. For best performance use the correct slant six specific BBD. If you are ordering a new one specify one for a 1978 Plymouth Volare Station wagon.

Reed,the print on those articles was a little small to read.In a nut shell can you tell me the difference between the two carbs?Does the 318 have a little more cfm's?wouldnt the 78 /6 bbd be a smog carb. :cry:

All I know is I put a 318 BBD on and it runs like a champ.However I will admit that the choke has a little catch in it when the motor cools,so it doesnt close all the way.But heck I'm in warm southern Cal who needs a choke. :lol:

You should be able to download those pictures and print them out. Essentially, besides the choke, the Slant Six specific BBD has a slightly different vacuum and fuel metering system which gives it better throttle response and a slightly leaner mixture. It also has different fuel metering rods (different steps on the actual rods). It has a slightly different configurations of passages on the bottom of the carb as well.

Essentially, there are enough tiny differences between the two to make it worthwhile to track down a slant six specific BBD.

Here is a list of the big difference between the 318 BBD and the Slant Six BBD:

(1) Slant six carb has idel mixture restrictors in the main idle circuit. Keeps the mixture from being too rich.

(2) Smaller main venturi for increased vacuum signal. Throttle bores are the same between 318 and 225 BBDs, but ther 225 has less cubic inches and therefore less vacuum sgnal at the ports in the carb. Therefore, the slant six BBD has smaller venturis.

(3) The slant six choke is offset in the air horn to proviode for leaner warm-up mixtures.

(4) The slant six BBD has a limited step-up pistom travel to limit emissions.

Like I said, little differences, but enought to warrant getting the correct carburetor.

And yet the 318 BBD bolts right on, with a change of the choke fulcrum to the \6 version, the choke works just fine, and with slight adjustments to the needles there is no differance in operation. The 318 BBD is good for 5% more hp over the \6 BBD (or so say the Racing Manuals).

if i were you, id prolly look for the super six bbd first, but if it wasnt readily available i wouldnt sweat running a 318 bbd. im running a 318 bbd on my car anyway.

I have never found a good /6 BBD in a junkyard(one did actually run but had bad throttle shaft bushings). They were either missing or the throttle/choke rods were frozen in place. I have used 3 different 318 BBD's and haven't had any problems with them. I also have never used the automatic choke. when I did my super six conversion I wanted to clean/adjust the choke and snapped the bolt head off, so I just went manual. My advise: find a 318 BBD and if it looks good/clean try it out. Rebuild kits are around $15 if you think it may need it first.

Hey Reed,
Thanks for that info,very interesting & informative.Appreciate it.
I could see how the slant bbd carb could be a snappy,crisp,clean running carb.

Maybe that extra shot of gas from the 318 bbd will lean out with some NOS!! :wink:

Thanks JZ

Hey, all I'm saying is that for a stock slant six in everyday driving the factory recommended carb is probably best. I don't think Chrysler would fo through the expense of designing and contractig with Carter to tool up for and produce a slant six specific carburetor unless there ws good reason for it. If you are going to be buying a replacement BBD or upgrading an otherwise stock motor to a Super Six, if you order the carb from a parts store you might as well pay for the right carb.

Well my question is what jetting / metering rod choices do I have? I am running a highly ported head with Hooker headers and duals with a crossover. I am worying about running lean. Right now my pipes are pretty black. When I want max acceleration I have to lift my right foot. BTW still have the stock cam/valves.

As far as metering rods go, I don't knwo of any suppliers of aftermarket one. However, I do believe that post 77 BBDs have jets that will interchange with Carter AFBs or Edelbrock Performer carbs.
