Chevrolet offered two versions of this 454 cubic inch v-8; LS5 and LS6. They could crank up an impressive 360 and 450 horsepower respectively. The LS6 has since been regarded as the last gasp of the muscle-car era and quite an impressive one at that. No other muscle car would match the 4-barrel carburetor, sweeping roof and bulged look of this monster on wheels.
Less than 70 of these were ever built. Not only did it have the most powerful engine, but also became the rarest production car that has ever been made by Chevrolet. The iconic 427 V-8 engine was capable of producing more than 430 horsepower.
