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:
“To me, the black black woman is our essential mother—the blacker she is the more us she is—and to see the hatred that is turned on her is enough to make me despair, almost entirely, of our future as a people.”
—Alice Walker (b. 1944)
“We lay long in the immense tide
Of shade and shadowy desire
And saw the dusk assail the wall,
The black surge, mounting, crash the stone!
Companion of this lust, we fall,
I said lest we should die alone.”
—Allen Tate (1899–1979)
“A new disease? I know not, new or old,
But it may well be called poor mortals’ plague:
For, like a pestilence, it doth infect
The houses of the brain ...
Till not a thought, or motion, in the mind,
Be free from the black poison of suspect.”
—Ben Jonson (c. 1572–1637)
