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:
“Magnified one thousand times, the insect
Looks farcically human; laugh if you will!
Bald head, stage-fairy wings, blear eyes,
A caved-in chest, hairy black mandibles,
Long spindly thighs.”
—Robert Graves (1895–1985)
“It’s not like I was out there running and not knowing what’s going on in the country. I knew what was going on, but I felt this is not something that is going to bog me down and not let me participate. The only way I was going to make a difference for myself or any other black person is to say the hurdles were there and do what I had to do.”
—Wyomia Tyus (b. 1945)
“On the middle of that quiet floor
sits a fleet of small black ships,
square-rigged, sails furled, motionless,
their spars like burned matchsticks.”
—Elizabeth Bishop (1911–1979)
