Chevy SBC/BBC V8 Small Cap Ready-to-Run Distributor with Female Cap

The TSP Small Cap Ready-to-Run Distributor with Female Cap for the Chevy SBC and BBC combines the compact small cap design and Hall Effect trigger of the JM6701 with a female terminal cap — the socket-style connector widely known in the vintage Chevrolet community as a "points-style cap" for its visual resemblance to a traditional points-era distributor. For builders restoring a 1955–1957 Chevrolet, early Camaro, or other vintage build to a stock-appearance underhood while running fully electronic ignition, this is the correct unit — modern Hall Effect electronics inside, classic points-style cap outside.

Engine fitment covers the complete Gen. I Chevrolet small block V8 (262–400 CID) and the standard-deck Mark IV big block V8 (396, 402, 427, and 454 CID) in carbureted applications. The small cap design fits engine bays where a large-cap HEI distributor would interfere with the firewall, air cleaner, or other components — a documented issue in pre-1975 cars and trucks where the compact cap footprint clears the firewall without body or accessory modifications.

Female terminals require matching plug wires. The female cap sockets accept male-pin spark plug wire boots. Verify your replacement or upgraded plug wire set uses male-pin boots before ordering. If your wire set uses female-socket boots, the male terminal cap version (JM6701) is the correct choice.

The multi-pole Hall Effect reluctor trigger provides a precise, maintenance-free electronic ignition signal with no points, no condenser, and no routine contact maintenance. An external ignition coil rated at 35,000 volts or higher is required — coil is not included. No separate ignition control box or CDI unit is needed.

 

Female Cap vs. Male Cap — Which Version Do You Need?
This listing (JM6701F) and the companion listing (JM6701) are the same small cap Ready-to-Run distributor in every functional respect — same engine fitment, same Hall Effect trigger, same specs, same price. The only difference is terminal gender on the distributor cap.

Female terminals (this listing) are recessed sockets that accept male-pin spark plug wire boots. Male terminals (JM6701) are protruding pins that insert into female-socket wire boots. Before ordering, check the terminal type on your existing or replacement spark plug wires. If the wire boots have a male pin that inserts into the cap, this female cap version is correct. If the wire boots have a female socket that slides over a pin on the cap, the male terminal version (JM6701) is correct.

The Points-Style Cap Look
The female terminal cap on a small cap distributor is widely known among vintage Chevrolet builders as a "points-style cap" — the female socket design closely resembles the appearance of the traditional points-era distributor caps used in 1950s and 1960s Chevrolet V8 engines. For concours-oriented restoration builds and engine bays where a stock-look underhood is a priority, the female cap version provides that classic appearance while running fully modern Hall Effect electronic ignition inside the housing. You get the look of a period-correct distributor cap with none of the maintenance of a points system.

Why the Small Cap Matters
The small cap design is the other key advantage of both the male and female versions of this distributor. In many pre-1975 builds — particularly 1955–1957 Chevrolets, early Camaros, and other applications where the engine sits close to the firewall — the large cap of an HEI distributor physically contacts the firewall or cowl and requires modification to fit. The small cap footprint of this unit clears those spaces cleanly without body modifications.
