Questions about replacement Carbs for that fit Super Six Intakes;

1) Does anyone have thoughts about good replacement carbs for the Carter BBD that came stock with Super Sixes?

The only other bolt up carb for that type of application is the Holley 2280 if you can't get a BBD...after that you'll need to do a bit of shadetree engineering and use some adapters to get other carbs to bolt up....


Here's a 'mock-up' of a supersix intake with a mr. gasket #1937 adapter and a pinto plenum top with the Pinto Holley 5200 progressive carb on top (Weber clone...)



Kickdown linkage becomes another problem too....

Using Mr. Gasket adapter plates there are a large number of carbs you can use, but only the BBD, Holley 2280, and Edelbrock performer (or Carter AFB) carb will hook-up to the kickdown linkage with no modifications. Possible carbs arethe Holley 5200 from pintos, mustangs, and early k-cars (as DI pointed out) the Holley 2300 two barrel found on 360s and 383s (you *might* be able to use the factory kickdown with this carb, I haven't ever tried to mock it up but it may work), the Holley 2305 staged two barrel, Weber downdraft carbs (see www.prolinefuel.com ), Rochester 2MV (thiese may be a bolt on replacement for the BBD, in the late sixties I think some were used on Mopars but double check), Holley four barrel carbs.

To use the Edelbrock performer/Carter AFB carb on a SUper SIx manifold I got a Mr. Gasket two to four barrel adapter. I had to grind one corner of the adpter down to clear the throttle linkage assembly. To hook up the kickdown I moved the linkage piece which runs between the carb and the kickdown rod from the inboard side of the rod to the outboard side of the rod and it hooked right up. Most of these carb will require modification to your throttle linkage and kickdown linkage, plus fabrication, to work properly. THat said, with a little tuning and creativity you can get just about any carb to work on your slant.

Thanks for both of your replies, I've learned a lot. My application is a 1967 Clark Cortez motorhome, which used a 225 Industrial Slant Six having a Carter YH (single barrel) sidedraft carb. The motor is coupled to a 4 speed manual transaxle. I've been looking for ways to economically increase the available power and have recently bought an aluminum Super Six intake manifold without a carb, which is why a posted the question about carbs.
I'm assuming the kickdown linkage mentioned is what shifts the automatic transmission into a lower gear when you floor it. I won't need to worry about that, but I will need to fabricate new accelerator linkage as the stuff that operates the existing carb I doubt will work. If anyone is curious what this motorhome looks like here is a link to check out: http://stormpages.com/cortezer/cortezn.htm
