Product Details

Features

  • Coil-in-cap HEI distributor cap and rotor set, black finish
  • Brass terminals for clean, reliable spark transfer
  • Fits 8-cylinder GM-style internal-coil HEI distributors only
  • Not compatible with external-coil HEI or non-HEI distributors

Description

This HEI distributor cap and rotor set refreshes spark transfer on 8-cylinder GM-style coil-in-cap (internal-coil) HEI distributors, in a black finish. Brass terminals help maintain clean contact between the cap, rotor, and HEI-style plug wire ends.

This is specifically for internal-coil (coil-in-cap) HEI systems — it is not compatible with external-coil HEI distributors or non-HEI distributor caps, which use different terminal layouts and cap designs. Verify your distributor type, cylinder count, cap attachment style, and spark plug wire terminal ends before ordering.

Commonly used for Chevrolet small block and big block HEI conversions, GM street rod and muscle car ignition upgrades, and custom HEI distributor refresh or replacement projects.


Applications
Fits 8-cylinder GM-style coil-in-cap (internal-coil) HEI distributors; common on Chevrolet small block and big block HEI conversions, GM street rod and muscle car ignition upgrades, and custom HEI distributor refresh projects.

Compatibility
Not compatible with external-coil HEI distributors or non-HEI distributor caps — these use different terminal layouts and cap designs. Verify distributor type, cylinder count, terminal layout, and coil-in-cap compatibility before ordering.

Q&A

Will this fit any HEI distributor?
No — this is for 8-cylinder GM-style coil-in-cap (internal-coil) HEI distributors only. It's not compatible with external-coil HEI distributors or non-HEI caps, which use different terminal layouts.

How do I know if my distributor is coil-in-cap or external-coil?
Check whether your ignition coil is built into the distributor cap itself (coil-in-cap) or mounted separately (external-coil) — these require different cap and rotor designs.

Is this the blue version, or are other colors available?
This listing is specifically black. Blue, red, and clear versions of this same cap and rotor set may be available as separate listings.

What's the terminal material?
Brass.

Does this include the rotor, or just the cap?
This kit includes both the distributor cap and a matching rotor.
