That’s exactly right: the words say this is a GT390, meaning a Mustang equipped with the legendary 390 cubic inch V8. However, what lies under the hood tells a bigger story.

The engine installed is actually a Ford unit with 428 cubic inches, fed by two large carburetors. Considering the fact that it’s a new engine, or at least rebuilt with few miles on it (according to the seller), we believe this unit produces no less than 400 horsepower. Consequently, even though it’s paired with the C6 automatic transmission, which steals at least 20% of the power at the wheels, there’s still plenty of fun to be had.

The Marti Report, essential for these cars that have now reached significant valuations, confirms that, aside from the engine, the rest of the car matches the specifications, including the stunning Candy Apple Red paint. We don’t consider it a concours-level example, but a beautiful one ready to be enjoyed on the road, as it doesn’t suffer from the “too beautiful to drive” syndrome.
