Overview
CK7787 is a premium kit that services all three carburetors in production Mopar Six-Pack or Chevy Tripower sets with all ethanol-compatible components made in the USA to OEM specifications.
Included in the Kit
Top-quality components including leak resistant, die-cut, Nitrile-coated metering block and bowl gaskets, throttle body, flange and air cleaner mounting gaskets as well as all other internal gaskets, power valve for the center carburetor, needle/seats complete with retaining nuts and lock screws (a Carburetor Doctor exclusive!), 30 cc GFLT accelerator pump diahragm, clips, idle mixture screws and printed instructions. GFLT pumps are made from a Teflon-like material that resists practically all fuels and many solvents and is very durable.
Fitment & Identification Tips
- Carb numbers: Please check the Holley LIST number stamped on the rear of the main body of the carb. See our guide on Holley numbers for more information.
- Compatibility: For production 3 X 2 setups with vacuum secondary operated carbs. There were also over-the-counter Six Pack sets sold through Dodge dealers that had mechanically operated secondary carbs. These are very rare today. They take different kits and floats. Please contact us if you have a set like this.
- Floats: The center carb takes the brass float F7007. Outer carbs use a similar Nitrophyl float, but with a shorter arm, which is F7119.
