A 1970 Chevrolet Chevelle built by a shop called Backyard Specialties runs a supercharged Kong Performance LSX rated anywhere from 750 to 900 horsepower — nearly double the factory LS6’s 450. The build rides on a Speedtech Performance chassis engineered decades after the body ever left Chevrolet’s factory.

A 1969 Camaro SS that looks bone-stock is hiding a 502-horsepower GM Performance crate engine, a Tremec six-speed, and a full Detroit Speed Pro-Touring chassis underneath. Carburetors are gone in favor of modern EFI, and the suspension borrows hardware straight from the C6 Corvette — without changing a single body panel. It’s proof a big-block Camaro can be brought fully into 2026 without losing what made it a legend in 1969.
