- Direct fit for Holden V8: 253/304/308
- Machined aluminum housing with steel gear for durable timing control
Description
Upgrade your Holden V8 — 253, 304, or 308 CID — with this Pro Series Pro Billet distributor, built with a magnetic pickup trigger for use with a compatible external ignition box and coil. This setup is designed for higher-output ignition systems on Commodore, Monaro, Kingswood, Torana, and Statesman applications.
The housing is machined aluminum with a steel drive gear best matched to cast iron hydraulic or solid flat-tappet camshafts, and rotation is clockwise. Requires a compatible external ignition box and a coil rated at 35,000 volts or higher; also requires a 12-volt electrical system with an alternator and is not compatible with generator-based charging systems or vehicles still running an active ballast resistor in the ignition circuit — the resistor should be removed or bypassed as part of installation. Timing is set through mechanical advance only.
What Is a Pro Billet Distributor?
A Pro Billet distributor uses a magnetic pickup trigger but, unlike Ready-to-Run designs, requires a separate external ignition box in addition to an external coil rather than housing that control on board. This setup is common in higher-output or race-oriented ignition systems where the buyer wants to pair the distributor with a specific external box and coil combination rather than an all-in-one unit.
Performance Benefits
The magnetic pickup trigger delivers consistent, wear-free timing signal without the point drift of older breaker-point systems. Because the ignition box and coil are external and separately selected, this setup allows the ignition system to be matched to higher-output requirements than a self-contained distributor typically supports on the Holden 253/304/308 platform. Mechanical advance handles the timing curve, keeping the system straightforward to set up and tune.

Engine Fitment
COMPATIBLE WITH
HOLDEN V8
• 4.1 L / 253 in3
• 5.0 L / 304 in3
• 5.0 L / 308 in3
NOTES
• Designed for carbureted Holden 253 and 308 V8 applications produced from 1969 onward.
• The 253 was available from 1969–1984 (carbureted); the 308 was available from 1969 onward in carbureted form through the VL Commodore (1987).
• The 304 is a destroked variant of the 308 introduced in 1985 for motorsport homologation — verify fitment before ordering on 304 applications.
• This distributor requires a separate external ignition box — not a ready-to-run unit.
• Not compatible with Chevrolet 307, 327, or 350 V8 engines that were optionally used in early Holden HK, HT, and HG models — those are American small block engines requiring a different distributor.
• Distributor gear is most compatible with cast iron hydraulic or solid flat tappet camshafts; consult camshaft manufacturer for recommended gear material before installation.

Q&A
Do I need an external ignition box with this distributor?
Yes. This Pro Billet distributor requires a compatible external ignition box in addition to an external ignition coil. Unlike Ready-to-Run or HEI distributors, it will not operate without an ignition box.
What direction does the rotor turn on this distributor?
Clockwise, viewed from above, matching the standard rotation direction of the Holden 253, 304, and 308 V8 engine family.
What type of advance does this distributor use?
This distributor uses mechanical (centrifugal) advance only. Three advance bushings and four advance springs are included, allowing you to customize the advance curve for your engine combination.
Does this distributor include a coil or ignition box?
No. Neither the ignition coil nor the ignition box is included. This distributor requires an external ignition coil rated at 35,000 volts or higher and a compatible external ignition box, both sold separately.
What distributor gear is included, and will it work with my camshaft?
This distributor includes a steel distributor gear, which is best suited for cast iron hydraulic or solid flat-tappet camshafts. If your engine uses a roller or other specialty camshaft, verify the recommended distributor gear material with your camshaft manufacturer before installation.
Emissions Notice
This Top Street Performance (TSP) product is designed for racing and off-road competition use only. It is not legal for use on public roads or emissions-controlled vehicles and does not comply with federal, state, or local emissions regulations. The buyer assumes all responsibility for legal use and installation.
What is a Emissions-Controlled Vehicle?
"An emissions-controlled vehicle is any vehicle equipped with a factory-installed emissions control system designed to reduce air pollution. These systems include catalytic converters, oxygen sensors, EGR (Exhaust Gas Recirculation) valves, and diesel particulate filters (DPF). Most vehicles manufactured after 1975 are considered emissions-controlled and must comply with federal and state emissions laws when used on public roads."
