My father and I have an 1964 MG B Roadster which he turned into a race car in mid 80's. He has since retired to help out in running the events. I have taken over driving the car in Sprints and Hillclimbs until I can afford to go racing.
I also help a mate out who has been racing his MG B GT (4 cylinder) for the last 2 1/2 years and developing that. (The white GT)
Just while im on the racing thing over here in MG Racing Victoria there is an 'open' class which allows a lot of modifications and here is the current fastest car and quite possibly on of if not the most winningest (not many words to say that) B V8 Roadster in the world...He has currently gone in pursuit of a 'Marque Sports Car championship against Porsche GT2/3's, Ferrari 360 GT and those sort of cars...so its sprouted big wings)
