Jaguar XJ8L with a LS3

Matt Farah recently took Karl Muth’s amazing 1999 Jaguar XJ8L out for a spin. Karl originally purchased the Jag off eBay for $1,201 and since then has completely transformed it into the type of Jaguar he felt it should have been. Karl started by replacing the factory 4.0 L V8 with a 6.2 L LS376/525 crate engine that received a Lingenfelter LS9 head conversion. This increased power to 575 horsepower at the crank or 488 horsepower to the wheels and give the car a better power-to-weight ratio than a F-Type. Another really cool upgrade was the open-gate T-56 Magnum six-speed transmission. Karl says there is about $38K in parts on this build. Watch below as Matt really enjoys himself.

  1. Wow. Congratulations to Karl for crafting such an amazing package. What an outstandingly tasteful and refined end product. I personally love the look of these cars but have traditionally avoided them due to my perceived factory drivetrain and electrical challenges. Is there a build thread for this project?
