A 1961 Pontiac Catalina Ventura fitted with a 421 cubic-inch Super Duty V-8 engine — Pontiac's highest-output unit of the era, rated at 405 bhp and paired with a Borg-Warner T-10 four-speed gearbox and Safe-T-Track rear axle. Though not a factory SD 421 recipient, the car underwent a frame-off restoration in California during the late 1980s and was subsequently held by noted collector Milton Robson before entering the Andrews Collection in 2010.

Maintenance & restoration

  1. Restoration

    Frame-off restoration carried out in California during the late 1980s; included installation of a 421 Super Duty V-8 in place of the original engine, a repaint to black, a change to a green interior, fitment of a T-10 four-speed transmission, and a Safe-T-Track rear axle with 4.10:1 gearing. Work was executed with factory-correct standards as the primary objective.

    Restoration performed by or under the direction of Ed Giolma; the car was not originally delivered with the SD 421 engine.

Roy reviews and verifies every registration personally.

Each chassis record is compiled from public auction archives and links to its source material. Ownership, competition and maintenance entries are extracted from those catalogue listings by an LLM, which can make mistakes — please contact us with any corrections. The summary is Legacy Metrics’ own writing; we do not reproduce catalogue text.

“Full” and “partial” documentation labels indicate how well each entry is corroborated in the underlying sources, not an audit of the car’s physical paperwork. Names of recent or living owners are withheld for privacy.
