Dodge 600 Series Truck 1974 on D3F and D5N 1-5 Ton HEMI 6 Cylinder W/ AIR Extractor (FX-766) Fits DODGE.
Category: Extractors and headers


The MPI Automotive FX-766 is a six-cylinder HEMI extractor set listed to fit the Dodge 600 series 1-ton truck (D3F and D5N) from 1974, with air. It replaces the factory exhaust manifold at the cylinder head.
An extractor, or header, swaps the cast factory manifold for tuned-length tubes that merge downstream, aiming to reduce back-pressure off the head. On the inline HEMI six in this Dodge truck it's a single bank of tubes at the front of the exhaust. The 'with air' note refers to the air-equipped variant of the platform. We can't publish power or sound figures for the FX-766, because the supplier doesn't.
The FX-766 is listed to fit the HEMI six-cylinder Dodge 600 series 1-ton (D3F and D5N) from 1974, in the air-equipped configuration. Confirm your exact engine, chassis code and whether yours is the 'with air' build before ordering. We treat it as 'listed to fit' rather than guaranteed, because feed data on trucks this age can be incomplete.
Oak Flats Muffler Men fits truck extractors in-house. On these older Dodge trucks we check head-face condition, stud access and how the extractor mates to the existing system before committing. Send your truck's details and we'll confirm the FX-766 and book the work.
The FX-766 is an MPI Automotive part with a recommended retail of $583.11. As a header for an older commercial six it may need to be ordered in, so ask us about lead time when you book.
