WANT TO PUT DUALS ON AN OLDS SMALL BLOCK?
What I am listing are the combinations that
can be used on a small block for true duals.
Meaning, not having to use a block off plate.
These manifolds do not have the dividers like
the more desirable W/Z's, but neither do the
crossover X-mans. Besides, you can't use a Z
manifold on a small block.

When the 442 first came out in 1964 as an option, it meant 4-Barrel Carb - 4 Speed trans - Dual Exhaust. Then in 1965 it was changed to 400 Cubic Inch Engine - 4 Barrel Carb - Dual Exhaust with the introduction of the 400 engine as a standard engine for the 442. That description stayed that way until 1968. In 1968 the Hurst Olds came with a 455 engine, however, the standard for the 442 was still a 400 cubic inch engine. In 1970 the 442 came standard with a 455 cubic inch engine so the first four no longer had anything to do with the engine size. However, in 1968 the 442 became it's own model with a special VIN, so the 442 became a special Olds all by it's self. One more bit of 442 trivia. It was originally a police option that the public could order, the model designation was B-O9.
