That's because Bill Devin was involved!
But this car is not a Devin...

1958 Echidna Special
John Staver, Ed Grierson and Bill Larson were responsible for the Echidna, a racecar named after an obscure Australian anteater.
Based largely around the Corvette. Each car started by shortening a Chevrolet frame by about twenty inches then narrowing it by six. With added rigidity in the frame, they used stock Chevrolet front suspension arms with coil springs and narrowed a stock Chevy Posi-Traction rear axle. Brakes were the Corvette drum brake type with metallic linings. Custom castings were made for the drums which included 96 fins cooling fins.

All correct.
Apparently 3 were built in all, using a fiberglass body made by Bill Devin, whose product was both lightweight and functional.
competing against the likes of Lister-Jaguars, Ferrari Monzas etc and Maserati 450S's and D-Type Jaguars the Echidnas started 35 races in two seasons, 8 of which they won overall with 17 class wins.
