Jaguar is currently working on the latest iteration of its stylish XJ sedan, and that car is going to be quite important for future Jag models. But what if you couldn't be bothered with following Jaguar's ethos of quiet traditionalism? Modifying a Jaguar seems almost as unholy a thing as slapping a body kit on a classic Ferrari, but some of these builds are simply epic. Recently, we compiled a list of our favorite tuned Jags ever, but that list may have been finished a little too early because the car we're featuring today certainly deserves a special mention. Fitted with a 540 cubic-inch V8 with plenty of added sauce, this classic 1970 Series 1 XJ6 is a monstrous sleeper with insane power.

But there's a lot more to this build than just a ridiculous 8.8-liter V8 with 300 horses of nitrous and a total rating of over 1,000 horsepower, as you can probably tell from that unusual front end. The car has seen the fitment of the entire front clip from a 1967 Chevy Camaro while the rear received a nine-inch axle. To help put the excessive power to the floor, the XJ6 has been fitted with coilovers and a four-speed automatic, and they've certainly helped: the owner, John, claims a personal best quarter-mile time with the car as 9.85 seconds at 140 mph. But unlike so many other capable drag cars, this one could happily park front and center of just about any aftermarket tuning show and looks stunning from every angle.

Sure, purists will despise the fact that the hood has been cut and had a massive power bulge fabricated, but there are some classy touches in the car too. The steering wheel is trimmed in leather, and while the dashboard looks straight out of a racecar, the seats are from an XJS. It's a pretty comprehensive build, with John saying that he spent around $15,000 on the paint alone with the build cost (so far) at around $100k. The motor alone would cost around $25,000 to replicate with its custom cams and other parts, but we think this was money well spent.
