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:
“A terrible, beetle-browed, mastiff-mouthed, yellow-skinned, broad-bottomed, grim-taciturn individual; with a pair of dull-cruel-looking black eyes, and as much Parliamentary intellect and silent-rage in him ... as I have ever seen in any man.”
—Thomas Carlyle (1795–1881)
“The secret lies, I think, in his intimate knowledge of the people he is addressing be they black or white, and in the forthrightness with which he speaks of those things which hurt and baffle them.... He allows them their self-respect—indeed, he insists on it.”
—James Baldwin (1924–1987)
“If violence is wrong in America, violence is wrong abroad. If it is wrong to be violent defending black women and black children and black babies and black men, then it is wrong for America to draft us, and make us violent abroad in defense of her. And if it is right for America to draft us, and teach us how to be violent in defense of her, then it is right for you and me to do whatever is necessary to defend our own people right here in this country.”
—Malcolm X (1925–1965)
