Holden EH/EJ, Frequently Asked Questions

What’s the difference between the EJ and the EH?

The EJ (1962-1963) and EH (1963-1965) share the same basic platform, but the EH is a significant improvement. The EH has a subtly wider body with more glass area, revised styling, improved suspension tuning, and, crucially, the optional 179ci Red Motor engine that the EJ never had. The EJ was only available with the 149ci engine. The EH also introduced the S4 trim level with a 4-speed manual floor shift, and front disc brakes became available. The EH is the more desirable car in every dimension except price, the EJ is more affordable and offers a similar (though less refined) driving experience.

What is the Red Motor?

The Red Motor is Holden’s first overhead-valve engine family, introduced with the EJ in 1962. It replaced the Grey Motor sidevalve engine that had powered every Holden since 1948. The name comes from the red paint used on early production blocks (later versions were painted gold or other colours). The Red Motor was produced in three displacements: 149ci (2,438 cc), 161ci (2,639 cc, introduced in later models), and 179ci (2,932 cc). It’s a pushrod inline-six with a cast-iron block and head, and it’s renowned for its durability, willingness to rev, and responsiveness to modification. The Red Motor family served Holden until the mid-1980s.

Which engine should I look for, 149 or 179?

The 179ci every time, if your budget allows. The 179 produces approximately 115 hp compared to the 149’s 75 hp, that’s a 53% increase, and it’s immediately noticeable behind the wheel. The 179 transforms the EH from a pleasant car into an exciting one. It has more torque for relaxed cruising, more power for overtaking, and a more characterful engine note. The 149 is perfectly adequate if you just want gentle motoring, but the 179 is the engine that made the EH famous.

How reliable is the Red Motor?

Extremely reliable. The Red Motor is one of the toughest engines Holden ever produced. The iron block and head are nearly indestructible. The pushrod valve train is simple and robust. The bottom end, crank, rods, bearings, is conservatively engineered and will last hundreds of thousands of kilometres with regular oil changes. The main wear items are valve guides, valve stem seals, and bearings, all of which are cheap and easy to replace. A well-maintained Red Motor will easily outlast the body it’s installed in.

Can I run an EH/EJ on unleaded fuel?

Yes. The Red Motor was the first Holden engine designed with hardened valve seats that can tolerate unleaded fuel without a lead replacement additive. This is a significant advantage over the Grey Motor cars. Use 91 RON unleaded as standard. The 179 engine benefits from 95 RON if it’s been tuned or has a higher-compression head.

What makes the EH S4 special?

The S4 was Holden’s first driver-focused trim level. It came standard with the 179ci engine, a 4-speed manual gearbox with a floor-mounted shifter (rather than the column-shift 3-speed on other models), bucket seats, a full instrument cluster with tachometer, and optional front disc brakes. The S4 was the enthusiast’s EH, the one you bought if you cared about driving. In 2026, the S4 is the most sought-after EH variant for driving enthusiasts. A good S4 with the 4-speed manual commands a significant premium over equivalent Special or Standard models.

What’s an EH Premier worth?

The Premier was the top of the EH range, full luxury specification with the 179 engine, power steering, comprehensive interior trim, and every available comfort feature. In 2026, EH Premier values range from $15,000-25,000 for a project, $25,000-45,000 for a driver-quality car, and $50,000-120,000+ for excellent or concours-quality examples. Original, low-kilometre Premiers with documented history command the highest prices. The Premier is the blue chip of the EH range.

Are EH parts easy to find?

Yes, the EH has the best parts availability of any early Holden, thanks to its massive production run of approximately 252,000 units. Mechanical parts (engine, gearbox, suspension, brakes) are readily available from specialist suppliers like Rare Spares and Restoration Industries. Body panels are more challenging but still available in reproduction form for high-demand items. Secondhand parts from wreckers and the club network are also a valuable source. The EH parts ecosystem is mature and well-established.

How does the EH compare to the Ford Falcon of the same era?

The EH’s main competitor was the XL and XM Ford Falcon. The Falcon had a larger six-cylinder engine (144ci and 170ci) and more interior space, but the EH’s 179 Red Motor was more powerful and more refined than the Falcon’s engine. The EH handled better, had better brakes (with the disc brake option), and was generally considered the more modern and desirable car. The EH outsold the equivalent Falcons by a significant margin. The Ford-Holden rivalry was already intense by the early 1960s, and the EH’s success was a major blow to Ford’s Australian ambitions.

Did the EH race at Bathurst?

Yes, and very successfully. The EH debuted at the 1963 Armstrong 500 at Mount Panorama and was immediately competitive against the Ford Falcon. The 1964 race saw EH Holdens dominate, with the 179-powered S4 models proving particularly strong. The EH’s combination of reliability, adequate power, and good handling made it a natural endurance racer. Many of the EH’s Bathurst entries were driven by privateers, ordinary enthusiasts who drove their cars to the circuit, raced them, and drove them home. This grassroots motorsport tradition was central to the Armstrong 500’s character.

Can I increase the power of a 179 Red Motor?

Yes, and the 179 responds beautifully to modifications. Common upgrades include: extractors and a free-flowing exhaust ($300-600), a performance camshaft ($150-300), twin SU or Weber carburettors ($500-1,200), cylinder head work (port and polish, larger valves, $500-1,000), and electronic ignition ($100-150). With these modifications, a 179 can produce 140-160 hp, a substantial improvement over the stock 115 hp. The Red Motor’s iron block is strong enough to handle these power levels reliably.

For serious performance, the 179 can be bored and stroked to 186ci or even 202ci using components from later Holden engines. The Red Motor family shares the same block architecture, so displacement increases are straightforward.

Is the EH suitable as a daily driver?

It can be used for daily driving, but it requires some adjustment in expectations. The brakes (especially on drum-brake cars) need more pedal effort and stopping distance than a modern car. The steering is slower and less precise. There are no seatbelts (unless retrofitted), no ABS, no airbags, and no modern crash protection. The ride is comfortable for a 1960s car but firm by modern standards.

That said, the EH is a more practical daily prospect than an FJ/FC. The Red Motor is reliable, parts are available, and the 12-volt electrical system (unlike the FJ’s 6-volt) can comfortably power headlights, indicators, and a modern radio simultaneously. If you’re comfortable with the safety limitations and willing to drive to the car’s capabilities rather than modern expectations, an EH can be a rewarding daily driver.

What oil should I use?

Use 15W-40 or 20W-50 mineral oil. Penrite HPR 15 (15W-60) is popular among EH owners. The Red Motor has generous bearing clearances designed for mineral oils. Do not use thin synthetic oils, they can leak past old seals and don’t provide the same protection in these engines. Change the oil every 5,000 km or 6 months, whichever comes first.

What clubs should I join?

The EH Holden Car Club is the primary marque-specific club, with chapters in most states. The Holden Car Club of Australia (HCCA) covers all models. The EH owners’ club is one of the largest and most active classic car clubs in Australia, with regular meets, shows, rallies, and a strong parts trading network. Club membership also provides eligibility for club registration (conditional registration), which significantly reduces registration costs for cars used primarily on weekends.

How bad is the rust on these cars?

It’s the primary concern for any 60-year-old Australian car. The EH rusts in all the usual places: floor pans, sills, lower guards, boot floor, A-pillars, and door bottoms. The severity depends on where the car has lived, a car from inland Queensland or South Australia will be in far better condition than one from Melbourne or Tasmania. Every purchase inspection should prioritise the body. Use a magnet to check for hidden filler and a screwdriver to probe for soft metal. A solid body is worth infinitely more than a fresh engine.

Can I convert an EJ to EH specification?

Mechanically, yes, the 179 engine, 4-speed gearbox, and disc brakes from an EH will bolt into an EJ. The body panels are different (almost every external panel changed between EJ and EH), so you can’t easily make an EJ look like an EH. Some owners fit EH running gear into an EJ body to get the mechanical improvements at a lower purchase price. This is a practical approach for a car you want to drive rather than show, but it won’t fool a knowledgeable buyer, the VIN and data plate will always identify the car as an EJ.

Should I buy an EH or save up for a Monaro?

These are very different cars for different purposes. The EH is a compact, nimble six-cylinder sedan with modest performance and an engaging driving experience. The Monaro is a larger, V8-powered muscle car with serious performance. The EH is more affordable, easier to maintain, and lighter on fuel. The Monaro is faster, more dramatic, and more valuable.

If you want an affordable entry into classic Holden ownership, the EH is the better choice. If you want raw performance and are prepared for significantly higher purchase and running costs, save for the Monaro. Many enthusiasts own both, the EH for weekend drives and shows, the Monaro for special occasions.

What’s the long-term investment outlook for the EH?

Strong. The EH has been appreciating steadily for over two decades and shows no sign of slowing. S4 and Premier models in original condition lead the market, but even base-model sedans have seen significant value increases. The EH benefits from its cultural significance (it’s arguably the most beloved early Holden), its massive production run (which ensures a large community of owners and enthusiasts), and the general trend of rising classic car values in Australia. Buy the best one you can afford and enjoy it, the value will take care of itself.

Are automatic EH cars worth buying?

Yes, though they’re less desirable than manuals. The 2-speed Powerglide automatic is adequate for the 149 engine but robs the 179 of much of its character. Manual EH cars command a 20-40% premium over automatics in equivalent condition. If you want a relaxed cruiser and don’t care about performance, an automatic EH is a pleasant car. If you want the full EH driving experience, the 4-speed manual with the 179 is the combination to seek out. Converting an automatic car to manual is possible but involves significant work (pedal box, gearbox crossmember, driveshaft, floor modification for the shifter).

Where can I find a good EH to buy?

The EH owners’ clubs are the best starting point. Club members who are selling cars generally know the car’s history and are realistic about its condition. Online classifieds (Carsales, Facebook Marketplace, Gumtree) have listings, but exercise caution, photos can hide a lot of rust. Always inspect in person. Car shows and swap meets are another good source. The established EH community means there are knowledgeable people who can help you assess a car, don’t be afraid to ask a club member to accompany you on an inspection.
