Jack,
You might also have a look at:

Since, in the case of many post 1997 trads, a lot of the gear will be Ford- derived, another good source of information is

www.burtonpower.co.uk
The Burton site may well be useful for comment on Ford engines such as the Zetec, Duratec and Sigma

A source which ( justifiably) gets mentioned regularly on TM is John Worrall and Liz Turner "Original Morgan" which essentially goes up to 1992 ( There is a second edition dated 2003 but it adds little to the first)

If you haven't seen this, then more details are to be found on this thread :
