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:

“Some burn damp faggots, others may consume
The entire combustible world in one small room
As though dried straw, and if we turn about
The bare chimney is gone black out
Because the work had finished in that flare.”
—William Butler Yeats (1865–1939)
“there’s a kind of lust feeds on itself
Unspoken to, unspeaking; subterranean
As a black river full of eyeless fish
Heavy with spawn; with a passion for time
Longer than the arteries of a cave.”
—Allen Tate (1899–1979)
