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:
“I myself saw furious with blood
Neoptolemus, at his side the black Atridae,
Hecuba and the hundred daughters, Priam
Cut down, his filth drenching the holy fires.”
—Allen Tate (1899–1979)
“If there is a man white as marble
Sits in a wood, in the greenest part,
Brooding sounds of the images of death,
So there is a man in black space
Sits in nothing that we know,
Brooding sounds of river noises....”
—Wallace Stevens (1879–1955)
“This will be a black baby born in Mississippi, and thus where ever he is born he will be in prison ... If I go to jail now it may help hasten that day when my child and all children will be free.”
—Diane Nash (b. 1938)
