Holden motor

The Holden motor is straight-six engine produced by General Motors–Holden's in Australia between 1948 and 1986. Initially dubbed the "Grey" motor alluding to the colour of the cylinder block, later iterations came in the form of a "Red", "Blue", "Black" and the four-cylinder "Starfire" engine. These engines were fitted to all Australian-designed Holdens of the same years, and the four-cylinder "Starfire" notably found its way into the Toyota Corona XT130.

Grey

The "Grey" motor built between 1948 and 1962, earned its name as the engine block was painted grey. This overhead valve engine was first fitted to the Holden 48-215 and mated to a three-speed manual transmission. A three-speed GM "Roto-Hydramatic 240" automatic transmission was optionally fitted in the latter EK and EJ series. The engine was based on a Buick pre-World War II design, and saw only minor changes throughout its 15-year life.

It displaced convert|132.5|cuin|L|1|lk=on in its original form, and was bored out to convert|138|cuin|L|1 when the FB series was introduced in 1960. It made convert|60|bhp|kW|lk=on at 5000 rpm, providing superior performance than competing four-cylinder Austin, Morris, Vauxhall and Ford of Britain vehicles. Due to the low compression ratio (7.5:1) they were able to revolve quite fast and effortlessly. Due to their sheer ubiquity, they were popular for racing, and were fitted to many open-wheelers, as well as racing Holdens. With the motors' low-end torque, they also found their way into boats and machinery such as forklift trucks.

This engine ran a nine-port non-crossflow cast iron cylinder head (three port inlet, four ports exhaust in a siamese layout), and was fed by a single barrel Stromberg carburettor and fitted with a traditional points distributor and ignition coil. The ignition system was six volts to match the 48-215 and FJ's six volt negative ground system, as was the starter engine. The earliest grey motors (approximately 100,000) were fitted with Delco-Remy accessories, although Lucas and Bosch equivalents throughout the motor’s lifetime replaced these.

The very first production grey motor (1948) was number 1001, and they continued in a single sequence until July 1956, when the prefix "L" was introduced.Loffler (2006), p. 284] The change affected all engines numbered L283373 and above, signifying the 12 volt negative ground engines as fitted to the all new FE model.Fact|date=June 2008 The prefix "U" was introduced for motors with the original electricals as fitted to the run-on FJ utility and panel van models, which ended in February and May of 1957 respectively. The change was effective from engine U283384. The prefix "B" was introduced and the number sequence reset with the introduction of the convert|138|cuin|L|1 displacement engine, and ultimately this was replaced by a "J" prefix for motors fitted to EJ vehicles in 1962.

Red

Superseding the "Grey" motor, the "Red" motor was manufactured between 1963 and 1980. Denoted by the cylinder block painted red, the engine debuted in the Holden EH in capacities of convert|149|cuin|L and convert|179|cuin|L producing convert|100|bhp|kW and convert|115|bhp|kW respectively. This was a power increase of 33 per cent and 53 per cent over the previous motor.

Blue

The "Blue" specification debuted in the 1980 VC Commodore.cite web | url = http://www.uniquecarsandparts.com.au/car_info_holden_commodore_vc.htm | title = Holden Commodore VC | publisher = Unique Cars and Parts | accessdate = 2007-06-15]

Applications

* 1980–1981 Holden VC Commodore
* 1981–1984 Holden VH Commodore

Black

The "Black" specification was introduced in the 1984 VK Commodore.Fact|date=March 2008 In the VL series of 1986, Holden ceased the tradition of employing Australian-made and designed six-cylinder engines, instead opting for the Nissan "RB30" engine. This came because pending emission standards and the requirement for unleaded fuel made it difficult to re-engineer the engine. [Robinson (2006), p. 25]

Applications

* 1984–1986 Holden VK Commodore

Starfire

This 1.9 litre powerplant, known as the "Starfire" engine, was effectively Holden's existing 2.85 litre 173ci straight-six with two cylinders removed. Peak power output is convert|58|kW|hp|lk=on, with a 17.5 second acceleration time from 0-100 kilometres (0–62 mi). [cite web | url = http://www.uniquecarsandparts.com.au/holden_commodore_VC_technical_specifications.htm | title = Holden Commodore VC Technical Specifications | publisher = Unique Cars and Parts | accessdate = 2008-02-07] This variant's performance meant the need to push the engine hard leading to fuel consumption similar to the straight-sixes.

Applications

* 1980–1981 Holden VC Commodore
* 1981–1984 Holden VH Commodore
* 1979–1982 Toyota Corona (XT130)
