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:
“The fact that white people readily and proudly call themselves “white,” glorify all that is white, and whitewash all that is glorified, becomes unnatural and bigoted in its intent only when these same whites deny persons of African heritage who are Black the natural and inalienable right to readily—proudly—call themselves “black,” glorify all that is black, and blackwash all that is glorified.”
—Abbey Lincoln (b. 1930)
“Personality is the glitter that sends your little gleam across the footlights and the orchestra pit into that big black space where the audience is.”
—Mae West (1892–1980)
“Richard. Give me a calendar.
Who saw the sun today?
Ratcliffe. Not I, my lord.
Richard. Then he disdains to shine, for by the book
He should have braved the east an hour ago.
A black day will it be to somebody.”
—William Shakespeare (1564–1616)
