Show-Quality Holley 4782 & 4783 Carburetors Rebuilt for Mopar 340 Six Pack Power

Check out these beauties — a freshly restored trio of Holley carburetors built to bring your Mopar 340 Six Pack roaring back to life. This isn’t some cookie-cutter rebuild, this is a factory-correct, show-quality setup featuring Holley 4782 and 4783 mechanical secondaries. No vacuum assist here, just pure throttle-driven power the way Dodge engineers intended. Each carburetor in this set has been fully disassembled, acid-etched to original finish specs, and rebuilt in-house with all new internals. The throttle shafts are line-reamed and brass-bushed to eliminate lean idle issues caused by wear, while all hardware has been properly re-plated for authenticity — no paint, no shortcuts. Wet flow tested and dialed in, they’re ready to bolt on with little to no adjustment. If you’re building a Super Bee, Duster, or anything rocking a 340 Six Pack setup, this is the rip-and-grip solution your project deserves.

This professionally restored Holley Six Pack carburetor set includes part numbers 4782 and 4783 — designed specifically for Mopar 340 Six Pack engines. These are mechanical secondary carburetors, built for maximum throttle response and raw performance, without relying on vacuum-assisted components. Ideal for 1970 Dodge Super Bee, Plymouth Duster 340, ‘Cuda, or any serious small block Mopar build, this setup is restoration-correct and ready to perform.

Each carburetor is completely disassembled, chemically boiled, and acid-etched to restore the original factory finish — there are no painted parts here. The throttle shafts are line-reamed and precision brass bushings are installed to correct common wear issues that cause lean idle or throttle hesitation. All hardware is re-plated to its original appearance, and all internals are brand new. Once reassembled to factory specs, each carburetor is wet flow tested for optimal fuel delivery and drivability.

Also included: optional fuel lines and linkage, ready to bolt on with minimal tuning required. Whether you’re restoring a numbers-matching show car or building a track-ready tribute, this Holley 340 Six Pack carburetor set delivers the correct look, the right sound, and the performance that Mopar fans expect.

At Custom Rebuilt Carburetors, the secret to our unmatched restoration quality starts with something most shops can’t offer — a massive, deeply organized parts department filled with rare, discontinued, and OEM-correct components. When others say it can’t be fixed, we find the part that makes it possible. From original Holley metering blocks to vintage Rochester linkages and obscure needle-and-seat assemblies, we’ve spent decades sourcing, cataloging, and stocking the parts that bring classic American carburetors back to life.

Whether you’re rebuilding a Mopar Six Pack, a Tri-Power GTO, or a single-barrel Carter from a post-war pickup, we don’t just get close — we get it right. Every restoration we complete uses parts that match the original spec and era, ensuring the correct fit, fuel delivery, and finish every time. That level of accuracy is only possible when you have access to the real hardware, not cheap overseas replacements or guesswork improvisation. When performance, originality, and long-term reliability matter, our inventory becomes your unfair advantage.
