4. 1971 Oldsmobile 442 W45 (455)
By 1971, Oldsmobile’s 442 evolved into a proper performance machine, earning the “W45” RPO code for its almighty 455-ci V8. Generating a stout 365 hp and 510 lb-ft of torque, the W45 featured a forged crank, high-flow heads, and dual Carter four-barrel carburetors atop a high-rise intake.
The Olds engineers also equipped it with heavy-duty springs and sway bars, transforming the sizeable Cutlass-based coupe into a surprisingly nimble brute. Even with its boat-like heft, a W45 442 could dispatch 0-60 mph in about 5.8 seconds. Blackout trim, hood tachometers, and bucket seats completed the package, earning it near-instant classic status.
