Hi, Sujit
In answer to your query, very likely. I never got really close to engineeri=
ng variances because I was in Export Sales but part of the job was to study=
and remember all the Engineering Change Bulletins and Service campaign cha=
nges. It makes sense to have an engine plate that would cover both engines =
and especially for Stag. What many people don=E2=80=99t know is that the St=
ag was originally going to have the TR6 2498cc engine as standard for all m=
arkets except North America where the V8 was to be a standard fitting with =
the V8 also being optional for all other markets. The decision to fit the V=
8 for all markets was taken very late in the day. I doubt there would be di=
fferent engine mounts for the in-line or V8 because quite a large number of=
Stags in the UK have been retro fitted with the 2498cc engine, suitably tu=
ned with twin SU carbs, a. TR5 cylinder head and camshaft and they are just=
a quick as the V8. The only thing missing is the V8 noise. Upgrading the a=
xle ratio from the original 3.7:1 unit in favour of one from the fuel injec=
ted saloon of 3.45:1 is another improvement, especially with a four speed B=
org Warner or ZF slush box from a Volvo or BMW.
As you may know, the Stag body was a shorter version of the larger saloon c=
ar whose monocoque body was exceptionally rigid. I do clearly recall the to=
rsional rigidity of the saloon was exceptional for its day, requiring 6,500=
lbs/ft of torque to twist it one degree. By Michelotti revamping the saloo=
n into an open top tourer, much of that rigidity would be lost and that is =
why the =E2=80=98T=E2=80=99 bar was fitted. It wasn=E2=80=99t quite as twis=
t resistant as the saloon, but good enough. At least you didn=E2=80=99t hav=
e to call on brute strength to line up the soft or hard top to engage the l=
ocking pegs on the screen rail.
Hope this helps.

Hello Jonmac,
Thanks for your email. On the Stag, the engine appears level. The offset is=
taken up by the engine plate. I dont have my parts book with me but was th=
at engine plate repurposed from a Triumph 2000, 2.5 as there are some oddit=
ies on it which don't match up with the bell housing on the Stag.

The in line six engine was tilted by six degrees on the Triumph 2000 and 25=
00 to achieve a low bonnet line. As the Stag was originally planned to have=
two engines - the 2500 six and the V8, the position of the engine mounts w=
as clearly never changed.

If it is does anyone know why?
