3.0L quad-cam V8, four-valve-per-cylinder heads, Bosch K-Jetronic fuel injection, ~310 bhp

A 1977 Ferrari 308 GTB assembled to Michelotto Group B competition specification for the US market, originally acquired by Herb Wolf and supplied through American importer Angelo Pedretti. The car was built using authentic Michelotto components — including rose-jointed suspension and uprated Brembo brakes — and the quattrovalvole engine was rebuilt around 2013 by Motion Products. FIA HTP was obtained in October 2011, and the car later entered a European private collection where it has remained since approximately 2013.

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.
