In 1957, Vince Piggins oversaw Chevy's skunkworks, Southern EngineeringDevelopment Company (SEDCO) in the Atlanta, Georgia, area. It built manyChevy and Corvette racers, including 10 fuel-injected 150s complete withsix-lug wheels, big brakes, rollcage, boxed A-arms, two shock absorbersper wheel, and much more. The cars did so well in NASCAR competitionthat they were outlawed, hence their slang term--Black Widow. (Widowmeaning all dressed up and no place to go). All '57s then had to competewith a 220hp, single Carter four-barrel carb. Note the fuel-injected150s had F.I. script and flags on the rear fins, not the front fenders.Why? So the competion could better remember who out-ran them.
