| Post subject: | super six carb options? |
hi, I have been driving my 1979 van for a long time with the single barrel carb, I have had a 2 barrel cast iron intake just laying around waiting for a bbd 2 barrel carter for a slant six for a year. My single barrel is just getting worse, I got no power and Im getting 10 miles to the gallon. Now I know I've been needing to change my axle gear ratio but as far as the motor goes I really want to put this super six set up on. Now my question is, can I bolt up my 2 barrel intake and just use a bbd of a 318 with or with out re-jetting, or could I find some other brand 2 barrel altogether? |

You can PM SlantSixDan to see if he still has any. Do you have the kickdown for the two barrel already or are you running a manual transmission? If you are running an automatic, you will need to install an appropriate kickdown linkage, fabricate one, or install a cable type kickdown like the Lokar. CJ |

They are many choices for carbs. You can still find Carter BBD's that were stock Slant installs for Super Sixed vehicles. I like Webers myself. I have both the Weber 32/36 and Weber 38/38 and like them both, for different reasons. Slightly moe power and better mileage is the 32/36. More power for about the ame as stock mileage is the Weber 38/38. Regardless of what you do I can tell you that the Remflex gasket is the way to go to prevent vacuum leaks. My experience with a FelPro intake/exhaust gasket tells me that you may not get a full life span from it... |

I do have one or two new Holley 2280 Super Six carbs left on shelf; send me a PM if you'd like one. |

its a manual tranny, so dont need to worry about that kick down cable. what would be more dependable, and easer to tune and maintain, and get parts for the carter or webbers or the holley 2280? |

Now THAT is a loaded question! The stock carbs are reasonably priced and there is an adequate amount of "tuning" stuff for them as well. They are NOT made anymore however. Webers: New, still made, relatively expensive. Very tunable--in fact, perhaps too much, I can't stop fiddling with mine...tons of support in the form of jets, etc. A well tuned Weber is probably as close as you can get to fuel injection with out having fuel injection. The downside of a Weber is that they are somewhat exotic and you may not easily find mechanics that are familiar with them. You should be comfortable with working on them yourself... |

Holley jets are more easily available in a wider range of sizes than Carter jets. |

How do these holleys compare the the webers, are they close in power and milage and dependability? |

The Holley 2280 and Carter BBD were designed for original-equipment type service, which means they drop right on, hook right up, and give new-car type driveability--hop in, stomp gas, turn key, drive away--with good economy right out of the box. They can be tweaked (rejetted) to the degree needed for them to operate at a close match with whatever extremely nonstandard condition you might be operating (well above or below sea level, etc.). The Webers, as has been mentioned, are aftermarket carburetors. They are very much more tunable and tweakable than any of the OE carbs...but this practically means you have to spend a fair good bit of time and effort doing so to make 'em run well. Also there are hookup factors to consider (throttle and choke linkage, air cleaner fitment, etc.) -- all of which require adaptation. |

Wait a sec... So I can plop my supersix intake and Holley 2280 onto my motor and everything will just hook up perfectly (1920 1bbl originally)? I have the supersix kickdown, but don't I need a supersix or v8 accelerator cable? Rusty bolts have made me put off the inevitable upgrade for a long time. Maybe I'll give it a shot in the next few days |

I had to install an adapter plate for my Holley 2280, but it sounds like there was one with the right footprint to bolt right on to the intake manifold? |

If you had to use an adapter plate to mount the Holley 2280 on the stock two barrel intake, then you are not using a Holley 2280. The Holley 2280 was designed and used as a direct replacement for the Carter BBD. It has the exact same footprint and bolt pattern as the Carter BBD. Super Six article |
