The XK engine is the best part of this car actually and runs beautifully with the SU carbs. My desire was to keep the car as original as possible and I was not even fond of performing these modifications and if not for my bad back I would not have. Thank you for the suggestion though, FI certainly is technically superior, but I do like the the nostalgia of carbs! That said, the car is unbelievably better to drive now with the 5 speed, the electric assist steering and the boosted hydraulic clutch (videos coming soon :)
