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:
“It was common practice for me to take my children with me whenever I went shopping, out for a walk in a white neighborhood, or just felt like going about in a white world. The reason was simple enough: if a black man is alone or with other black men, he is a threat to whites. But if he is with children, then he is harmless, adorable.”
—Gerald Early (20th century)
“why
Do our black faces search the empty sky?
Is there something we have forgotten? some precious thing
We have lost, wandering in strange lands?”
—Arna Bontemps (1902–1973)
“But not the tallest there, ‘tis said,
Could fathom to this pond’s black bed.”
—Edmund Blunden (1896–1974)
