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:
“th’ other black and grave, wherewith each one
Is checker’d all along,
Humilitie:”
—George Herbert (1593–1633)
“Black women ... work because their husbands can’t make enough money at their jobs to keep everything going.... They don’t go to work to find fulfillment, or adventure, or glamour and romance, like so many white women think they are doing. Black women work out of necessity.”
—Wilma Rudolph (1940–1994)
“I thought when I was a young man that I would conquer the world with truth. I thought I would lead an army greater than Alexander ever dreamed of. Not to conquer nations, but to liberate mankind. With truth. With the golden sound of the Word. But only a few of them heard. Only a few of you understood. The rest of you put on black and sat in chapel.”
—Philip Dunne (1908–1992)
