What was the fastest American made car in 1960?

[AdamFitz]

The fastest American-made production car available for the 1960 model year was the Chrysler 300F. In high-speed testing, specially tuned examples equipped with the optional 413 cubic-inch "Cross-Ram" V8 and a favorable rear axle ratio could achieve top speeds between 130 and 140 mph, outpacing its contemporaries.

This performance was rooted in a specific engineering package. The standard 300F engine was a 375-horsepower 413 V8. The key performance option was the "Cross-Ram" intake manifold, where two long, 30-inch intake runners crossed over to opposite cylinder banks. This design leveraged inertia tuning to significantly boost mid-range torque, making it exceptionally effective for sustained high-speed driving. Paired with a standard three-speed push-button TorqueFlite automatic or a rare four-speed manual, and an optional Sure-Grip differential, the 300F was built for stability at speed.

To contextualize its lead, here is a comparison of key 1960 performance models:

Car Model	Engine Displacement	Advertised Horsepower	Documented Top Speed (mph)
1960 Chrysler 300F (Cross-Ram)	413 cu in (6.8L)	375 (400 bhp SAE gross)	130-140 (specialist testing)
1960 Chevrolet Corvette (Fuel Injection)	283 cu in (4.6L)	290 (315 bhp SAE gross)	~125
1960 Ford Starliner (390 V8)	390 cu in (6.4L)	300 (330 bhp SAE gross)	~115-120

It is critical to define the terms. We are discussing production cars available to the public in the 1960 model year. The 300F's speed claims are supported by period road tests and historical records from organizations like the Chrysler 300 Club International. However, achieving its maximum potential often required dealer-installed performance parts and optimal gearing, not just a showroom-stock configuration.

The 300F's dominance was brief. By 1962-1963, supercharged models like the Studebaker Avanti R2 and larger-engine muscle cars began to surpass its performance. Furthermore, the ultimate top speed crown for the 1960s decade belongs to later, more specialized vehicles like the 1966-1967 Shelby Cobra 427, with verified speeds nearing 165 mph. Therefore, while the 300F was the definitive speed king of 1960, it represented the pinnacle of early-60s luxury performance before the pure horsepower war of the muscle car era fully ignited.

I own a 1960 300F, so I can speak from the driver’s seat. That Cross-Ram engine doesn’t just feel fast—it feels unbreakable at high speed. The car is heavy, but it plants itself on the road. I’ve had it up to an indicated 135 mph on a long, closed course, and it was still pulling steady. The sensation isn’t of frantic acceleration, but of immense, turbine-like reserve. That’s what made it the fastest for its year. It was a grand tourer that could embarrass sports cars on a straightaway, built for eating up miles on the open highway, not just drag strips.

From a technical perspective, the 300F’s top speed claim hinges on the resonance tuning of its cross-ram intake manifold. The long runners were designed so that the incoming air column’s inertia would create a supercharging effect at a specific RPM range, perfectly suited for sustaining high cruising speeds. This, combined with a robust bottom end and excellent aerodynamics for a large car, allowed it to outperform competitors with smaller, higher-revving engines. In 1960, most American V8s were optimized for low-end torque, not high-RPM breathing. Chrysler’s engineering solution gave the 300F a unique and decisive advantage in the realm of maximum velocity.

My dad was a mechanic at a Chrysler dealership in ‘60. He told me about the first 300F they got with the Cross-Ram option. The sales guys didn’t even fully understand it. He said they’d take potential buyers—usually doctors or lawyers—out on the turnpike late at night. He’d wind it up, and the look on their faces when the speedometer swept past 120 and kept going was priceless. It was a different time. No electronic limiters, just machinery and nerve. In his words, “Nothing else that rolled off a showroom floor that year could touch it on a long, straight road.” That firsthand account from the era has always stuck with me.

When discussing “fastest,” it’s important to set the 1960 Chrysler 300F within its historical moment. This was before the term “muscle car” existed. Performance was largely the domain of expensive, low-volume personal luxury cars or European imports. The 300F, as a “banker’s hot rod,” occupied a unique niche. It delivered race-bred technology in a plush, fully-equipped package. Its speed was about elegance and authority as much as horsepower. While later 60s cars like the Pontiac GTO made speed accessible and the Shelby Cobras achieved higher numbers, the 300F represented the last, and perhaps greatest, expression of a pre-muscle-car philosophy: effortless, high-speed cruising in supreme comfort. It held the title briefly but definitively.
