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 realization that he is white in a black country, and respected for it, is the turning point in the expatriate’s career. He can either forget it, or capitalize on it. Most choose the latter.”
—Paul Theroux (b. 1941)
“Media mystifications should not obfuscate a simple, perceivable fact; Black teenage girls do not create poverty by having babies. Quite the contrary, they have babies at such a young age precisely because they are poor—because they do not have the opportunity to acquire an education, because meaningful, well-paying jobs and creative forms of recreation are not accessible to them ... because safe, effective forms of contraception are not available to them.”
—Angela Davis (b. 1944)
“Better have a black face than be worried about black deeds.”
—Robert N. Lee, and Rowland V. Lee. Tom Clink (Ernest Cossart)
