What was the V8 displacement of the 1957 Rambler Rebel?

The 1957 Rambler Rebel used a 327-cubic-inch V8.

This AMC V8 debuted in the special-edition 1957 Rebel, giving Rambler a compact performance car with substantially more power than its ordinary six-cylinder models. The Rebel’s engine used mechanical valve lifters and a higher compression ratio than the related 327s installed in some Nash and Hudson models.

The AMC 327 was not Chevrolet’s later small-block 327. AMC’s engine appeared in 1957, five years before Chevrolet introduced its own 327 V8. That shared displacement is one of the most common sources of confusion.

The Rebel’s 327 was paired with upgrades such as stronger front springs and a reinforced rear axle. Rambler built approximately 1,500 examples, and the model is often cited as an early American muscle car because it combined a relatively light body with a large, powerful V8.
