This paper is an account of my experiences building and racing Triumphs over the last ten years. A number of companies are mentioned in the text and this is intended as a sample of the many companies that exist to supply the Vintage Racing movement. Mentioning a company does not imply personal experience of that company or an endorsement of their products unless this is specifically mentioned. Likewise, there are many ideas, opinions and methods of performance improvement. I am covering those I have used or seen used, and there are many others not mentioned here.
