Chevrolet Impala 1961 SS 572 Convertible

The Impala SS badge traces back to a tiny handful of cars built in 1961, when only 142 out of roughly 491,000 Impalas left the factory with the all-new 409 engine that inspired the Beach Boys song a year later. This convertible ignores that history entirely, swapping in a modern 572 cubic-inch big block that dwarfs anything Chevrolet built for the street in period. Full custom interior work and red line tires round out a build that prioritizes raw output over originality. It’s a bold, unapologetic take on a legendary badge.

The red line tires….The 572 BIG Block under the hood…Full custom interior….The fit and finish you expect from a high end shop…. This 1961 Chevrolet Impala is as cool as it gets…..Check it out!!

The Impala SS badge on this car traces back to a very specific, very short window in Chevrolet history, and what’s sitting under this particular hood has almost nothing in common with what left the factory in 1961. Chevy only built a handful of genuine SS-package Impalas that first year, and an even smaller handful of those got the engine everyone actually wanted. This convertible skips all of that and goes a completely different direction with a modern 572 cubic-inch big block that dwarfs anything Chevrolet ever offered from the factory in a full-size car. So how did the SS badge get its start, and just how far has this build strayed from where it began?

The Birth of the SS Badge

Chevrolet introduced the Super Sport package late in the 1961 model year as a way to sharpen up the brand’s performance image, pairing it with an all-new 409 cubic-inch V8 that was itself a bored-out version of the existing 348. Out of roughly 491,000 Impalas built that year, only 453 got the SS package, and of those, a mere 142 actually left the factory with the 409 engine before production problems shut that combination down until 1962. That makes an original 409 SS from 1961 one of the rarest and most sought-after combinations in the entire muscle car hobby, and it’s the exact rarity that inspired the Beach Boys to sing about “409” a year later.

A Big Block Built for a Different Era

A 572 cubic-inch big block, the kind sitting in this convertible, wasn’t even a concept Chevrolet engineers were working with in 1961, it’s a modern aftermarket crate engine built for street and strip use decades after this body style left the factory. Dropping one into a car wearing the SS badge is a bold statement about priorities: this build isn’t chasing numbers-matching originality, it’s chasing raw output that would embarrass the original 409 several times over.

Full Custom, Full Commitment

Red line tires and a full custom interior finished to the standard of a high-end shop tell you everything about the intent here. This is a car built to be driven and shown, not tucked away as an untouched survivor. Whether you’re a purist who wishes it kept its original driveline or someone who appreciates a big block transplant done right, there’s no denying the fit and finish on display.
