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:
“To be black and an intellectual in America is to live in a box.... On the box is a label, not of my own choosing.”
—Stephen Carter (b. 1954)
“I wake and feel the fell of dark, not day.
What hours, O what black hours we have spent
This night!”
—Gerard Manley Hopkins (1844–1889)
“I can’t really hear the audience applause when I’m on stage. I’m totally immersed in the piece. But sometimes I get a lot of it and wonder, “Now, why did they applaud here?” If it’s a white crowd, they usually applaud because they think it’s a pretty movement. If it’s a black crowd, it’s usually because they identify with the message.”
—Judith Jamison (b. 1944)
