Oh Fountainhead of such unquestionable knowledge, may I most respectfully
suggest you do a quick spool-back and exclude the Stag V8? :)
It was a mountain of trouble on the cooling side of things and mostly caused
by the Purchasing Department at STI over-riding Engineering in provisioning
water pumps, radiators and cylinder heads of a quality that was inconsistent
with Engineering spec  - and  all on the grounds of cost. As a result, the
people responsible were fired and justly so. The only other fly in the
ointment was the foundry Birmid Qualcast, who supplied the cylinder blocks
that still had part of the casting cores embedded deep inside them and no
small amount of foundry sand blocking coolant passages. Apart from those
'minor' issues which effectively killed the Stag in its first two years
(some say less) I don't think it had other key problems. It's bete-noire was
cooling. Period.

Cheers, Jonmac
