Rare Vintage Italian Weber 42 DCOE 8 Carburetors – Matching Triple Set Maserati For Sale - New and Used

Rare Vintage Italian Weber 42 DCOE 8 Carburetors – Matching Triple Set (3K/3G).
Overview

Up for sale is an exceptionally rare, authentic set ofthree (3) Italian-made Weber 42 DCOE-8 side-draft carburetors, manufactured in Bologna, Italy.

Originally developed as factory equipment for theMaserati 3500 GT, these authentic Italian-cast "big body" side-drafts represent the high-water mark of vintage European performance induction. Today, matched triple sets in this condition are increasingly difficult to find. These are in good condition (see pictures) but will need a complete rebuild, cleaning, and new gaskets before they are used. Only the items pictures are included. Ask any questions. I will do my best to answer them.

Factory Production & Batch Matching

All three carburetors feature authentic original Bologna castings stamped42 DCOE 8. Crucially, they carry adjacent factory production batch stamps:

• Two (2) Stamped "3K"

• One (1) Stamped "3G"

Having closely matching batch codes confirms these carburetors were produced together in the same original manufacturing run. For high-end Maserati restorations or vintage race engine builds, matched factory castings ensure identical wall thickness, passage machining, and tuning synchronization. The air horns have scuff marks and a slight upwards angle. They are a tad longer than the ones I normally see with the DCOE carbs, but look correct for the 3500GT. See pictures for details.

Choke / Main Venturi Package Included

This sale includes a highly desirable dual-choke package featuring both standard and rare period-racing hardware:

1. Standard 32mm Main Venturis (Chokes):The original factory size specification for the Maserati 3500 GT setup.

2. Alternate 30mm Venturis (6 total):A second set of 30mm aluminum chokes .

Note: I took out all the internal components to check on the installed specifications. These were used on a race-prepped 240Z so most of the components do not match the originalfactory Maserati 3500 GT delivery specs.Circuit ComponentInstalled SpecificationMaserati Factory SpecNotesMain Venturi (Choke)32 mm32 mmFactory size included (plus extra 30mm set)Auxiliary Venturi3.53.5Factory OriginalMain Fuel Jet130135UpdatedAir Correction Jet200155UpdatedEmulsion TubeF11F15UpdatedIdle Jet45 F955 F2UpdatedAccelerator Pump Jet4545Factory OriginalPump Exhaust / BleedClosedClosedFactory OriginalNeedle Valve2.002.00Factory Original
