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 can’t really hear the audience applause when I’m on stage. I’m totally immersed in the piece. But sometimes I get a lot of it and wonder, “Now, why did they applaud here?” If it’s a white crowd, they usually applaud because they think it’s a pretty movement. If it’s a black crowd, it’s usually because they identify with the message.”
—Judith Jamison (b. 1944)
“As I was going by Charing Cross,
I saw a black man upon a black horse;
They told me it was King Charles the First—”
—Unknown. As I was going by Charing Cross (l. 1–3)
“Rain falls for centuries
Soaking the loose rocks in space
Sweet rain, the fire’s out
The black snag glistens in the rain
& the last wisp of smoke floats up”
—Gary Snyder (b. 1930)
