Ken, I think you will have to consult several sources.
I would strongly recommend Geoff Roe's "Bert Hadley, a son of Birmingham", available from the PWA7C. An excellent book not only in relation to your interest.
Canning Brown's "Austin Seven Competition History" will cover a great deal.
Roland Harrison's "Austin Racing History" is well worth consulting.
Bob Wyatt's "The Austin Seven" will give you a useful basis for your spreadsheet.
If you have the indices to the A7CA "grey mags" you can find some useful articles.
Chris Garner will be along in a minute with the ones I've missed....
I can't think of a single specific history of the twin cams but, if there is, someone will soon tell us!
Regards,
Stuart
