Guess the year, make and model!

This convertible’s color and stripe combination are the easy part of the guessing game – the real question is what’s under the hood. If it’s the LS6, you’re looking at one of just 4,475 ever built, an engine strong enough to beat a Road Runner 440 Six Pack and a Torino Cobra 429 in period Motor Trend testing.


Classic yellow convertible car with silver racing stripes.

The image gives you a few obvious clues: a bold factory color, a set of contrasting stripes, and a stance that only a handful of manufacturers ever nailed this well. What it doesn’t give away is the number sitting under the hood — a figure that separates a nice-looking Chevelle from one of the most sought-after muscle cars General Motors ever built. Get the year right and the engine option right, and you’re not just naming a car; you’re naming one of only a few thousand ever built with this specific combination.

The Engine Under That Hood

If this is the LS6-equipped 1970 Chevelle SS most enthusiasts hope it is, the 454-cubic-inch V8 underneath was rated at 450 horsepower at 5,600 rpm and 500 lb-ft of torque at 3,600 rpm, running an 800-cfm Holley four-barrel, 11.25:1 compression, and a forged steel crank and rods. Buyers could order it with a Muncie M22 “Rock Crusher” four-speed manual or a Turbo Hydra-Matic automatic, and in period testing by Motor Trend, the LS6 Chevelle beat both a Plymouth Road Runner 440 Six Pack and a Ford Torino Cobra 429, running 0-60 in 6.0 seconds and the quarter mile in 13.8.

How Rare Is Rare?

Only 4,475 LS6 engines were built for the 1970 model year, and Chevelle was the only model that got them — spread across coupes, convertibles, and even the El Camino pickup, with only a handful of convertibles and El Caminos believed to have received one. That scarcity is exactly why a correctly optioned LS6 Chevelle SS commands the kind of money it does today, and why guessing this one right feels like more than just a trivia win.
