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:
“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)
“... contemporary black women felt they were asked to choose between a black movement that primarily served the interests of black male patriarchs and a women’s movement which primarily served the interests of racist white women.”
—bell hooks (b. c. 1955)
“Quadroon mermaids, Afro angels, black saints
balanced upon the switchblades of that air
and sang.”
