1970 Chevrolet Chevelle SS Convertible Custom

This 1970 Chevelle SS convertible wears one of muscle car history’s most respected shapes, but there’s nothing 1970 about what’s actually driving it. Between LS6 mythology, six-figure auction results, and the modern hardware hiding under the skin, this build makes the case that restomods aren’t a compromise. They might be the smartest way to own this car.

The old look, the modern go, the best of each era!

A 1970 Chevelle SS convertible already turns heads on factory looks alone — that squared-up “Coke-bottle” body was Chevrolet’s answer to a muscle car war that was reaching its absolute peak. But this particular build isn’t chasing 1970 anymore. Underneath that unmistakable silhouette lives a drivetrain that would’ve been science fiction to the engineers who built the original LS6-optioned cars, and that contrast is exactly the point. Restomods like this one live in a strange, wonderful space where a car can look like it just rolled off a dealer lot in the Nixon era while driving like it was built last week. So how do you take one of the most respected muscle car shapes ever made and actually improve on it without losing what made it special in the first place?

1970 Was the Chevelle’s Peak Year, and It Showed

By 1970, Chevrolet wasn’t messing around with the Chevelle SS anymore. The range-topping LS6 454 was factory-rated at 450 horsepower and 500 lb-ft of torque, and depending on who you ask, that number was conservative — some estimates put the real output closer to 500 horsepower as it left the factory floor. Only a few thousand Chevelles were ever built with the LS6 package, which is part of why genuine survivors command serious money today, with well-documented originals selling into the hundreds of thousands. A convertible LS6 is rarer still, since most buyers chasing that kind of power wanted the stiffer, lighter coupe body.

Why Restomod Chevelles Bring Six-Figure Money Now

That original-era scarcity is exactly why builders don’t shy away from cutting into a 1970 Chevelle body to drop in modern power. A well-executed restomod convertible — think supercharged LT4 crate engines pushing 650-plus horsepower, six-speed manuals or built automatic overdrives, and four-wheel disc brakes hiding behind repro Rally wheels — lets an owner keep the exact factory stance and side profile while gaining the kind of stopping power and drivability the original LS6 buyers never had. Auction results back this up; clean restomod Chevelle convertibles have crossed the block for figures approaching $600,000, proof that the combination of period-correct looks and modern engineering isn’t just a fan favorite, it’s a legitimate collector category now.

The Custom Touches That Separate a Good Build from a Great One

What usually separates a forgettable restomod from a genuinely great one comes down to the details that don’t show up on a spec sheet — a dash reworked to hide modern gauges without looking aftermarket, subtle body-color bumpers, or a paint color pulled straight from the 1970 GM palette instead of something flashier. On a convertible like this, a power-operated top that folds cleanly and a properly trimmed interior with hidden climate control make the biggest difference in actually wanting to drive it daily instead of trailering it to shows. That’s the real appeal of the old-look-new-go formula: it’s not about hiding the modern parts, it’s about making sure nobody notices them until you mention it.
