Product Details
Features
- HEI-style distributor for the Chrysler Early Hemi (FirePower Gen I) 392 V8 only
- Internal 65,000V coil eliminates need for external coil or ignition box
- Correct fit for '57–'58 Chrysler 300, Imperial, New Yorker & Town & Country
- Not compatible with 331/354 early Hemi or 426 Hemi Gen II — 392 only
Description
This HEI-style distributor is built specifically for the Chrysler Early Hemi (FirePower, Gen I) V8 — 392 CID only. It integrates a magnetic trigger and a 65,000-volt internal coil, so there's no external coil or ignition box to source separately.
This distributor is not compatible with the 331 or 354 early Hemi, or with the 426 Hemi (Gen II) or modern Hemi engines — it fits the 392 FirePower exclusively. It also will not fit low-deck blocks. Confirm your specific early Hemi displacement before ordering, since the 331, 354, and 392 use different deck heights and distributor drive requirements.
This distributor requires a 12-volt electrical system with an alternator. It is not compatible with generator-based charging systems or vehicles still running a ballast resistor in the ignition circuit — the ballast resistor must be removed or bypassed before installation. Since the factory '57–'58 vehicles this engine came in were already built with 12-volt systems, most factory applications won't need a separate 12V conversion; this note primarily applies to earlier 6-volt vehicles receiving a 392 as a swap.
Factory vehicle applications for the 392 include the 1957–1958 Chrysler 300, Imperial, Newport, New Yorker, and Town & Country.
Performance Benefit
The 65,000-volt internal coil delivers stronger spark output than the factory points-style ignition originally used on these engines, supporting easier cold starts and more consistent spark across the RPM range. Both mechanical and vacuum advance are included, with a vacuum advance adjustment tool shipped in the box so the advance curve can be tuned for your specific engine and driving conditions.

Q&A
What applications is this distributor compatible with?
This distributor fits the Chrysler Early Hemi (FirePower Gen I) 392 CID V8 used in 1957–1958 Chrysler applications, including the Chrysler 300, Imperial, Newport, New Yorker, and Town & Country.
Will this distributor fit a 331 or 354 Early Hemi?
No. This distributor is designed specifically for the 392 CID Early Hemi and is not compatible with the 331 or 354 CID FirePower engines.
Will this distributor fit a 426 Hemi?
No. This distributor is designed exclusively for the Gen I FirePower 392 CID Hemi. It is not compatible with the 426 Street Hemi (Gen II) or any modern Chrysler Hemi engines.
Does this distributor include an ignition coil?
Yes. This HEI distributor features an integrated 65,000-volt ignition coil built into the distributor cap. No external ignition coil or ignition box is required. Simply connect a switched 12-volt power source for operation.
Does this distributor come with a vacuum advance adjustment tool?
Yes. A vacuum advance adjustment tool and installation instructions are included, allowing you to fine-tune the vacuum advance for your specific engine combination.
Will this distributor fit a low-deck block?
