You gotta love old Mustangs. The look, the smell, the tire-squealing torque – it’s all classic muscle car stimuli that’s sure to evoke something if you’re even the least bit interested in cars. As such, it’s a platform that’s seen a ton of reimagining over the years, from light modification to complete overhauls. This particular restomod falls towards the more extreme side of that spectrum, boasting an incredible 1,000 horsepower at the rear wheels. Responsible for the build is Timeless Kustoms, a speed shop based out of southern California, which took its outrageous pony car down the road a little ways to Jay Leno’s Garage in order to give the former Tonight Show host and lifelong car guy a looksee.

“Today’s featured vehicle,” Jay begins, “1965 Ford Mustang Fastback, so far from stock that it’s hilarious. This is exactly the kind of car that just gets the comments section going.”

What started as an unblemished six-cylinder coupe was transformed into what it is now through 10,000 hours of exhaustive tweaks, tuning, and modifications. Timeless Kustoms did a complete teardown before hitting it full force with the upgrades, and clearly, pulled no punches in executing the build.

But let’s get to the party piece under the hood. Providing motivation is a 5.1-liter Coyote V-8, which gets a supercharger and two turbos to stuff an insane amount of air into the cylinders.

At over 23 minutes, the video is a bit on the long side, but there’s plenty of footage of the build and a healthy amount of tech specs to get you excited for your own wrenching adventures.
