The Black specification was introduced in the 1984 VK Commodore. The black engine was produced in 3.3-litre form in carbureted and fuel-injected versions. The carbureted engine was almost identical to the previous blue engine, the main difference being in the use of computer controlled spark timing (EST) The ports were slightly wider spaced, meaning the manifolds will not simply interchange. The Bosch-injected version used a long-runner intake manifold and a conventional HEI ignition. It also had slightly different cylinder head intake ports for improved breathing.
In the 1986 VL Commodore, Holden replaced the Australian-made and designed six-cylinder engines with the Nissan RB30 engine. Pending emission standards and the requirement for unleaded fuel made it difficult to re-engineer the Australian engine.

Famous quotes containing the word black:
“Lo, thus, as prostrate, ‘In the dust I write
My heart’s deep languor and my soul’s sad tears.’
Yet why evoke the spectres of black night
To blot the sunshine of exultant years?”
—James Thomson (1834–1882)
“Magnified one thousand times, the insect
Looks farcically human; laugh if you will!
Bald head, stage-fairy wings, blear eyes,
A caved-in chest, hairy black mandibles,
Long spindly thighs.”
—Robert Graves (1895–1985)
“The brotherhood of men does not imply their equality. Families have their fools and their men of genius, their black sheep and their saints, their worldly successes and their worldly failures. A man should treat his brothers lovingly and with justice, according to the deserts of each. But the deserts of every brother are not the same.”
—Aldous Huxley (1894–1963)
