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:
“Civil Rights: What black folks are given in the U.S. on the installment plan, as in civil-rights bills. Not to be confused with human rights, which are the dignity, stature, humanity, respect, and freedom belonging to all people by right of their birth.”
—Dick Gregory (b. 1932)
“He hangs in the hall by his black cravat,
The ladies faint, and the children holler:
Only my Daddy could look like that,
And I love my Daddy like he loves his Dollar.”
—William Jay Smith (b. 1918)
“The monotonous dead clog me up and there is only
black done in black that oozes from the strongbox.
I must disembowel it and then set the heart, the legs,
of two who were one upon a large woodpile
and ignite, as I was once ignited, and let it whirl
into flame....”
—Anne Sexton (1928–1974)
