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.

“Thou art a beaten dog beneath the hail,
A swollen magpie in a fitful sun,
Half black half white
Nor knowst’ou wing from tail
Pull down thy vanity
How mean thy hates”

And there I see such black and grained spots
As will not leave their tinct.”

Innocence sweetens my last black breath,
Modesty hides my thighs in her wings,
And all the deadly virtues plague my death!”
