The Z28 performance package for the Camaro was created to compete in the SCCA Trans-Am Series.
The rules for the SCCA Trans-Am Series mandated an engine displacement of no more than 305 cubic inches, so GM engineers placed the crankshaft from the 283 V8 with a 3 inch stroke into the 327 V8 with a 4 inch bore, giving a resulting displacement of 302 cubich inches. The rev-happy engine with an 11:1 compression ratio and solid lifters was rated conservatively at 290 hp, but far more power could be coaxed from it with little effort.
This car features the JL8 4-wheel power disc brake option that replaces the stock 11 inch front disc brakes/rear drum brakes with 11.75 inch disc brakes on all wheels, as well as multi-leaf rear springs. The option cost $500, a sizable outlay for 1969, and only 206 Camaros from 1969 featured the package.
This car will be sold by Mecum Auctions in Monterey, California on August 18-20, 2016, right before the Pebble Beach Concours d'Elegance on August 21.

In 1966, the SCCA debuted an all-new racing series that would attract attention away from its popular Production racing classes and produce some of the best racing ever seen on American race tracks: the Trans American Sedan Championship, or Trans Am. Because it awarded not only a driver’s championship but also one for manufacturers, the series exerted the same level of influence on the factories’ pony-car offerings as NASCAR had on intermediates. The Trans Am presented a brand new venue for car companies to market their products, and Chevrolet began developing a special-performance package to homologate the new Camaro before it even entered dealer showrooms. The result was the Z28, which by 1969 had reached its fullest expression as a no-holds-barred performer. One of the most highly coveted features of the 1969 Chevrolet Camaro Z28 was the ultra-rare JL8 4-wheel power disc brake option, a $500 package that replaced the standard 11-inch front disc and rear drum brakes with 11.75-inch discs at all four corners and included multi-leaf rear springs. Confirmed in controlled testing by Chevrolet engineer Gin Huffstader, the result was vastly improved stopping power and decreased brake fade, just the ticket for the Penske Racing Trans Am team for whom the JL8 package was originally developed. The product of a 15-month frame-off restoration, this 1969 Z28 is one of only 206 Camaros built with the JL8 brake package. Complementing its Fathom Green paint and white stripes is a very handsome white-on-black houndstooth interior with the wood-grain steering wheel rim and accents, assist grip, molded door panels and bright pedal trim that formed the Z87 Custom Interior group. The special ducted hood opens to reveal the matching-numbers 302/290 HP solid-lifter engine, which is fitted with rare chambered exhaust. Other features on this brilliant restoration include front and rear spoilers, Rally wheels with Goodyear Wide Tread GT tires, power steering and console with Special Instruments.
