Yes, its an SU, off a Rover 2000. I have taken off the chrome fake airfilter trim off the old airbox and it now sits about 1 1/2" closer to the engine. Going to fit a 4" velocity stack on it and have to make up a throttle arm as there wasn't one on the carb when I got it.
Also have to fit a choke cable, think I will fit it on the bars.
