Hi Alan
In response to your question, yes my XJS-C is a V-12 circa 1986. It now has a total of 178,000 miles on it, despite the engine fire. The entire engine bay was a disaster from the flames requiring a lot of work. Along with rewiring the car after the fire, I changed the intake system to the “Growler” intake, along with 1″ heavy-duty anti-sway bars front and rear, and a Super-X large bore 1 3/4″ SS exhaust system. These changes are probably not everyone cup of tea, but they sure make the Jag run/drive better than ever, albeit with a bit more bark!
Thanks for the question.
Russ
