This classic Jaguar XJ has a 720-hp ungentlemanly secret

Forget Tawny Kitaen. If you want to make a Jaguar XJ rock, just do what this guy did: stuff a heavily modified and turbocharged General Motors V8 under the hood, and take it to the track.
The video calls this Series 1 XJ a sleeper, but with its open exhaust and obvious turbo whistle, the once-gentlemanly sedan is anything but. The owner says that the engine is GM LQ9 V8 that has been stroked to 402 cubic inches putting out around 720 horsepower with 12 pounds of boost (in standard form, this 6.0-liter V8 was used in the second-gen Cadillac Escalade). Check out the video below to see what that kind of power does for this classic Jaguar in the eighth-mile.

Jaguar F-Type Project 7 takes the D-Type to the 21st Century

One of the many big name debuts during the 2014 Monterey car week is this, the Jaguar F-Type Project 7, a stunning roadster inspired by Jaguar's legendary, finned D-Type sports car.
The Project 7 expands on the already appealing F-Type Convertible formula, further boosting the Jaguar Land Rover 5.0-liter, supercharged V8 to its most potent form yet - 575 horsepower - making this the most powerful production Jag in history. So equipped, the Project 7 is more cheetah than jaguar, roaring to 60 miles per hour in a rapid 3.8 seconds before reaching its electronically limited peak speed of 186 miles per hour.
Prices for the F-Type Project 7 start at $165,000, with customer deliveries slated begin in spring of 2015.
