In 1969, Chevrolet offered a wide range of engines for both the Camaro and the mightiest of these was the aluminum block, 427 cubic inch V8 known as the ZL1.When equipped in the small Camaro, it could run circles around most of the Corvettes on the street.

The ZL1 was Central Office Production Order 9560 (COPO) that could be specially ordered for an additional $4,160 over the base price of the Camaro. This internal ‘fleet’ order helped overcome the restrictions GM placed on Chevrolet to only offer engines smaller than 400 cubic inches in the Camaro. Since COPO was really meant for special paint and options on commercial vehicles, the ZL1s were not exempt from warranties and they were 100% street legal.

The ZL1 came at the request of Fred Gibb who wanted a more powerful option for NHRA drag racing. A minimum of 50 cars had to be made to go racing and eventually only 69 were ordered. It was intended only for professional drag racers that could recoup the expensive list price.

Gibb intended to sell the entire production run from his dealership in La Harpe, Illinois. His ‘what wins on Sunday sells on Monday’ ethos struck a chord with Chevrolet’s manager Pete Estes.

Offered at a price tag of $7,269, the ZL1 was almost twice the cost of a cast-iron V8. Fred had trouble selling the 50 which were worth over $363,000 combined. Many cars were redistributed through the Chevrolet dealer network and others had their engines removed to try out in different projects.

Only 13 ZL1s were sold directly by Fred’s dealership. Some were further prepared by the dealership and tuned by Dick Harrell. Around 20 cars were prepared for the NHRA Super Stock series, and when tuned right and with slicks could reach low tens in the quarter mile.

At the center of ZL1 was a fire-breathing V8 originally developed for the Can-Am Chaparral. It used cylinder heads similar to aluminum-head L88 engine, but had an entirely aluminum block with steel liners. Unlike the Can-Am unit, the ZL1 had wet-sump lubrication, K66 transistorized ignition system and accommodations for a mechanical fuel pump.

Fed by a single Holley 4-barrel, it was the most powerful engine GM offered to the public and produced around 500 honest horsepower. This was attached to a new positraction differential with larger pinion and axle gears. While 69 of these were included in the Camaro, only a handful came equipped in the Corvette.

The ZL1 Camaro started as a 396 SS body, but had the F4l suspension, ZL2 cowl-induction hood, heavy duty front springs, heavy duty front brakes and a four-speed sometimes ordered with the M21 close ratios. With the stock tires, the ZL1 could do the ¼ mile in the low 13 second range.

Many of the ZL1 Camaros received hard race lives and were rebodied or modified in drastic ways for racing.
