1964 Cooper Monaco CM/3/64

CM/3/64racingUnited Kingdom
Engine
Fuel-injected 327 cu-in (5.4L) Chevrolet V8, paired with four-speed BMC Huffaker transaxle

The Cooper Monaco CM/3/64 is one of only two examples from the 1964 batch fitted with Chevrolet power rather than the more common Ford V-8. Built for Jack Brewer of Elmira, New York, it was equipped with a fuel-injected 327 cubic-inch Chevrolet V-8 and a BMC Huffaker transaxle. The car competed in both SCCA and USRRC events over more than five decades, passing through seven known racing owners while retaining its original aluminum bodywork, chassis, and transaxle. A major overhaul in 2006 and a comprehensive mechanical recommissioning in 2018 keep it race-ready today.

This car's public record is built from its auction and competition history. Register your ownership and privately add your own records to make it a verified Legacy Metrics passport — provenance that backs your car's value at sale and gives your insurer evidence to price against. 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.
