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:
“Our inherent human charity and our religious beliefs will be taxed to the limit. No poor, rural, weak, or black person should ever have to bear the additional burden of being deprived of the opportunity of an education, a job, or simple justice.”
—Jimmy Carter (James Earl Carter, Jr.)
“Lo, thus, as prostrate, ‘In the dust I write
My heart’s deep languor and my soul’s sad tears.’
Yet why evoke the spectres of black night
To blot the sunshine of exultant years?”
—James Thomson (1834–1882)
“When a Jamaican is born of a black woman and some English or Scotsman, the black mother is literally and figuratively kept out of sight as far as possible, but no one is allowed to forget that white father, however questionable the circumstances of birth.”
—Zora Neale Hurston (1891–1960)
