In the muscle car wars of the late 1960s, rules were made to be broken and few broke rules better than Don Yenko. In 1967, while General Motors held the line at 400 cubic inches for the new Camaro, Yenko had other ideas. Partnering with racer and tuner Dick Harrell, he created the Super Camaro 450; a factory-fresh SS/RS transformed into a street-legal brute-packing Corvettes 427 big block. Though extremely limited production resulted in just 54 Yenko Camaros being completed and sold in 1967, this example (YS-703) is a standout even within that elite group.

Delivered new in Ermine White as a 396-equipped L78 SS/RS, this Camaro was shipped straight to Harrells Performance Center in East St. Louis, Illinois. There, the six-day transformation from stock to Super Camaro began: The original engine was yanked in favor of the fire-breathing L72 427, rated at 450 horsepower with 11:1 compression, a Holley 3910 four-barrel carburetor, aluminum intake, and free-flowing dual exhaust.

Harrell further fortified the drivetrain with a Muncie M21 close-ratio four-speed, heavy-duty clutch, and 12-bolt Posi rear end with 3.73:1 gears. A larger radiator, metallic brakes, custom-tuned suspension, and performance extras like traction bars, tuned headers, lightweight 15-inch wheels, and an NHRA-certified scatter shield completed the Super Camaro 450 package.

Despite its raw power, this car wore a gentlemans suit. The Rally Sport trim with hidden headlights and bright accents was retained, making it one of the especially rare RS-equipped Yenkos. Inside, a walnut-grain steering wheel, center console, and AM push-button radio added comfort to the chaos under the hood. From the outside, only a Corvette-style stinger hood and subtle 427 badges hinted at what lurked beneath.

Sold new on 1 August 1967 to Jay Kline Chevrolet in Minneapolis, Minnesota, YS-703 identified in Yenko inventory documents that accompany the sale has long been cherished by top-tier collectors. Its prior owners roster reads like a whos who of the muscle car scene: Kevin Suydam, Gary Holub, Wayne Schmeeckle, and Trans-Am racer Bill Ockerlund have each played a role in its story. As presented today, YS-703 wears a highly detailed, award-winning restoration executed under prior ownership by renowned Yenko Camaro authority Dave Tinnell of Daves Auto Service in Edmonton, Kentucky.

Now offered from a private family collection of American sports cars in the Pacific Northwest, this Super Camaro remains among the finest examples of Yenkos early work. Backed by a file of factory documentation and expert authentication, YS-703 is regarded as one of the most historically significant Yenkos in existence.To view this car and others currently consigned to this auction, please visit the RM website at rmsothebys.com/auctions/mo25/.
