Chevrolet
Camaro COPO 9560 ZL1

Why it matters

COPO 9560 put Chevrolet's all-aluminium 427 ZL-1 racing engine into the Camaro through a fleet-order loophole, sidestepping GM's ban on engines over 400 cu in in smaller passenger cars. Only 69 were built, making it the rarest and most extreme factory Camaro of 1969.

How rare is it?

Six separate kinds of rarity – never combined into one number.

Each kind of rarity is rated separately and never combined.

Production

Every figure says what it counts.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

Fred Gibb Chevrolet of La Harpe, Illinois, used the Central Office Production Order route in October 1968 to order 50 ZL-1 Camaros for drag racing; 19 more went to other dealers. Gibb's cars arrived on 31 December 1968, but at more than $7,300 on the sticker they sold slowly – Gibb himself sold only 13 – and from May 1969 Chevrolet took many back. Several dealers removed the aluminium engines or sold cars with iron engines, and Gibb's last new car was not sold until 1972. Gibb's car #1 later won the 1971 AHRA Pro Stock championship.

Identification guide

How to tell an original from a replica or later conversion.

Genuine cars have VINs of the form 124379N6xxxxx and appear on the Camaro Research Group's list of 69. Engine build codes are ML (4-speed) or MM (automatic) for Camaro ZL-1s. The rear axle is the special 4.10:1 positraction unit coded 'BE' rather than the regular 'BV'. Cars carry only a plain 'Camaro' fender emblem with no external engine badge, have 'Camaro SS' trim deleted, an AIR pump, no choke, and '427' written in crayon by assembly workers inside the fender extensions; Gibb's cars had black standard interiors and no radios.
