hi people, I just bought a XR3000 "FireBall" developed by Crane Cams and I was wondering what people think of these mondern ingnition sys ?? do you think they are worth the money ???? anyone who has installed them on a british car ??? well, I do hope that it is compatible with my so called "upgrated TR4A engine", with 87mm liner kit, oversized valves, valve porting, etc. hopefully it wont overheat, but i'll let you know when i start it, if i ever finish it.
