On the plus side, gone is the somewhat unreliable Jaguar V12 motor and in came an SBC 383 stroker. Its 6.3 liters of Chevrolet crate V8 madness develop in excess of 400 horsepower in naturally aspirated form. But the owner wasn't happy with that, so he bolted an upright blower to the 383 cubic-inch motor for added oomph. Vector in Holley 750 carbs, a Corvette exhaust manifold, and that it "runs fine on pump premium."
Notice the size of the rear tires. Ginormous 29x18 R15s are needed to keep the torque in check, as is the TH350 automatic transmission, the 2,800 rpm stall converter, and narrowed Ford 9-inch rear end. But the car isn't 100 percent perfect, or so the seller is telling us in his extremely detailed eBay listing.
The Pro Street Jaguar XJS at hand doesn't have wipers, the signal lights and horn aren't working, power window motors need to be changed, and the rear end "could use a new housing gasket." You can see from the photo gallery that the underbody is clean except for the rear end, but hey – it's a small and cheap fix.
Best of all, the drag racing XJS is $12,300 after 34 bids, which is almost $2k less than a Ford Fiesta.
