Quick Answer
The W-30 is the top performance package on the Oldsmobile 4-4-2, a cold-air-induction 455 V8 setup offered at its peak from 1970 to 1972. W-30 cars had outside-air induction, plastic inner fenders, and special tuning, and a documented W-30 is the most valuable 442.

The W-30 is the 442 to chase.

What it is

A factory performance package built around the 455 Rocket V8 with a cold-air (outside-air) induction hood, red plastic inner fenders, and hotter tuning. It was the muscle peak of the Olds A-body.

Buyer's note

Demand documentation. The W-30 tells, the hood, the inner fenders, the option codes, all need to line up, since the package is widely faked.
