If you are a lover of early Camaros, or muscle mass automobiles in general, then some of your favorites have to be the Yenko-modified examples, built for individuals who desired a lot more than what Chevrolet was keen to give by way of its dealers.

The development was termed a Yenko Tremendous Camaro, and they even offered a tuned variation that place out even additional electrical power.
This 1967 Chevrolet Yenko Camaro RS/SS coupe, one of 3 recognized to exist, is an early merchandise of the partnership in between racer Don Yenko and “Mr. Chevrolet,” Dick Harrell. A pioneer in the organization of constructing “vendor specials” to satisfy the pent-up demand for aggressive Chevrolet muscle cars and trucks, Yenko began by modifying 100 Corvair coupes for SCCA competitiveness. With the entry of Chevrolet’s new Camaro into the escalating effectiveness wars, Yenko hired Bowtie skilled Harrell to regulate the Yenko Chevrolet racing system and acquire custom made higher-functionality offers that unleashed the massive probable of Chevy’s growing assortment of midsize muscle mass cars and trucks.

Even more Yenko solutions provided Traction Learn traction bars, tuned headers, scattershield, and unique spark plug wires. It seems affordable today, but that was a whole lot of hard cash again in the mid-’60s.
A Corvette Stinger-model fiberglass hood replaced the first unit, and delicate Yenko 427 badges ended up added to the hood bulge and front fenders. Even though most Yenko Tremendous Camaros carried the L72’s factory ranking of 425 hp, a decide on couple of, which include this 1967 example, benefited from Harrell’s sizeable expertise to the tune of 450 hp at 6,000 RPM.
