Macker, my 4.2 litre Range Rover does that much! I've just been given a kit off a carb engined RR, not sure whats there yet, but I hope to fit it on my Commer. I've been using LPG on RRs for twelve years now, but always on injected engines, so doing it on a carburetter will be interesting. Can't do anything for a couple of weeks tho', as I'm up to me oxters replacing the woodwork on my Morris 1000. Watch this space!
