1970 was a watershed year in the history of American muscle. Most would agree that the muscle era hit its apex in 1970. Vying for the top of the pops was Chevrolet's Chevelle SS 454. The SS 454 carried Chevy's intermediate performance banner. The Super Sport package, Chevelle's highest performance option, was available in the hardtop Sport Coupe ($3,497) and convertible. ($3,697) The big block LS5 454-cubic-inch V8 produced 360hp in standard form. The LS6 produced a claimed 450 gross HP in solid-lifter, high-compression guise and cost a mere $263.30. 4,574 LS5s were produced in 1970. Of those, 91 were convertibles.

While not the uber top end LS6, they surely aren't giving these babies away. A 1970 LS5 Convertible made $ 185k in 2011 at Barrett Jackson. This example appears at Mecum.
