There is/was a manual by I believe "Triumph Tune" on the TR7 but I have no idea were the link is. I printed it off a few years ago but can't find where it is at the moment and just spent the last ten minutes looking for it to see if it had a link. I'll look harder later. It didn't talk a lot about the 8V engine but went into considerably more detail on the sprint 16V engine.
As far as I know no longer available, as are lots of parts mentioned in it.
