Inlet manifold is this off a GT6 / TR6?

[kartman24]

I bought this inlet manifold with a load of other spares about 25 years ago, can anyone tell me what it is off/fits? Most of the spares were Triumph so I am assuming this is Triumph also?
Many thanks for any help...........Martin

from memory, that is not a GT6 part

These were never standard but some tuners (Triumphtune, SAH etc) have made them and there has twice been a group buy via the TSSC. They come in two types a straight type to fit TR6 etc and a stepped down type to fit under the lower bonnet line of the GT6. From the photo this looks more like a straight one.

I don't think these are for a GT6, or any Triumph six cylinder head.

1/ they are too far apart.
2/ Triumph six manifolds, both inlet and exhaust, are held on by shared studs, witha bean-shaped load spreader under the nut. Both manifolds have wide flanges - these do not.
3/ They look as if they are designed to have studs through from the head on the same axis as the front, carburettor studs - the castings are cutawayfior acces to the stud ends.

But no idea what they are for!

You are right of course the studs are in the wrong place. Jaguar XK had a triple SU setup at one time and the ports are much wider spaced on that.

I discounted Jags, because they were cross flow, and thses look as if they had sopace between for exhaust ports, like a Triumph, but late Jag XK120s had equally spaced inlets, wide apart for water cooling ports:

But the studs are in the wrong place!
It's still a mystery!

Here is a shot of the ports where they bolt to the head.............Martin
