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:
“The legacies that parents and church and teachers left to my generation of Black children were priceless but not material: a living faith reflected in daily service, the discipline of hard work and stick-to-itiveness, and a capacity to struggle in the face of adversity.”
—Marian Wright Edelman (20th century)
“I’m afraid to look in the mirror. I’m afraid I’m going to see an old lady with white hair, just like the old ladies in the park. A little bundle in a black shawl just waiting for the coffin.”
—Paddy Chayefsky (1923–1981)
“Thus while I sit and sigh the day
With all his borrow’d lights away,
Till night’s black wings do overtake me,
Thinking on thee, thy beauties then,
As sudden lights do sleepy men,
So they by their bright rays awake me.”
—Sir John Suckling (1609–1642)
