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:
“Thus Winter falls,
A heavy gloom oppressive o’er the world
Through Nature shedding influence malign,
And rouses up the seeds of dark disease.
The soul of man dies in him, loathing life,
And black with more than melancholy views.”
—James Thomson (1700–1748)
“The body is no body to be seen
But is an eye that studies its black lid.”
—Wallace Stevens (1879–1955)
“... the Black woman in America can justly be described as a “slave of a slave.””
—Frances Beale, African American feminist and civil rights activist. The Black Woman, ch. 14 (1970)
