1969 COPO Chevelle

COPO Chevelle The Ultimate Sleeper

The Muscle Car war was at its peak in 1969. Other manufactures were offering cars with engines over 400 cubic inches like the Chrysler 440 and the 426 Hemi. So, Chevy decided to build a limited number of very special Chevelles with the 425 horsepower 427 cubic inch L72 engine. GM had a ban on engines over 400ci in mid-size cars. So, to circumvent the rule, they used the Central Office Production Order (COPO) system. This system was only used for special fleet orders for Taxis and Trucks.

However, only a hand full of people knew about this. And so, only 323 COPO Chevelles were built. The COPO cars came with the 427ci Engine, Al the upgrades of the L78 package and special heavy-duty rear axle with heat-treated 4.10:1 gears.

All COPO cars came with no special badging or engine emblems. From the outside, they look like a standard 300 Deluxe Chevelle.

The COPO Ran The Quarter Mile In The Low 13 Seconds. Making, These Cars The Ultimate Sleepers.
