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:
“And my eyes are blue;
So ferry me across the water,
Do, boatman, do!”
“Step into my ferry-boat,
Be they black or blue,”

“I only know that a rook
Ordering its black feathers can so shine
As to seize me senses, haul
My eyelids up, and grant
A brief respite from fear
Of total neutrality.”
—Sylvia Plath (1932–1963)
“Visit the Navy-Yard, and behold a marine, such a man as an American government can make, or such as it can make a man with its black arts,—a mere shadow and reminiscence of humanity, a man laid out alive and standing, and already, as one may say, buried under arms with funeral accompaniments.”
—Henry David Thoreau (1817–1862)
