5. Chevrolet El Camino SS
Straddling the line between muscle car and utility, the El Camino SS married pickup practicality with full-blown performance attitude. In the late 1960s, buyers could order a 396-cubic-inch big-block or, come 1970, the infamous 454-cubic-inch V8. Despite its truck-like bed, the El Camino SS carried the suspension and braking upgrades of its Chevrolet Chevelle SS stablemates, ensuring it could hustle off the line and handle sweeping turns.
The combination of a deep-grumble exhaust note and a functional load bed made it a unique muscle car statement: you could haul heavy loads by day and carve the quarter-mile by night.
