Twin SU carburettors

No but it was very very old.

Do you have a photo of them on the car, it would make life a bit easier. ;) I'd be tempted to say an old Triumph but the angle of the manifold is a bit confusing.

Yes, the angle is foxing me too.

Mini's had angled engine but the carbs were tilted the otherway towards the engine.

These are the biggest SUs ive ever seen, if it was a mini it would be about 2.5 litre :)

Looks like a very old pair of SU carbs from a triumph 6 cylinder 2.5litre??? Maybe a stag V8? Or an MGBGT v8? they had an odd manifold?

They are fitted on a manifold with only 4 ports.

That would cause a minor problem.... I didn't look at it... Just the carbs!

Some datsuns 4 cylinders had SU carbs???

And would have a strange amount of inlet ports

They aren't TR3/TR4 carbs. How about a Rover 2200TC?

I have since been told from someone from another group that you can tell what car they came from by the ID tag on the float bowl. This reads AUD533F, anyone know a web site I can punch this number in?

I think I have found a site, seems they are from a 1971-1979 2000 TC P6. the AUD 533F is the front and there is a AUD533R at the rear. here is the site if you are interested

My Jap SU's didn't have the round shoulder on the top, it had a quite sharp edge and turning marks could be seen on outside of the piston cover, SU saved cash by not machining the outside. L20T (T for Twin SU's) in my W reg Bluebird coupe was near vertical and I can't think of any Japanese cars with engines that were angled. Can't see the jets but on Jap ones the jet block is not adjustable, it just slid up and down to richen the mix for starting.

Marina 1750 TC?

This would almost certainly be a slant four engine, the manifold is too wide and too long to be one side of a v8 setup and the SU needs to be mounted vertically, generally. So the cylinder probably leans 45 degrees off vertical and this is done as a way to lower the overall height of the bonnet so it would be something with a reasonably streamlined shape, more than likely.

This engine could be transverse, e.g. like the Mini, or longitudinal and my guess (just a guess, I've never seen one close enough to recognise it) would be something like a Triumph Spitfire. Triumph used carbs like this and had a slant four engine.

Very odd. The carbs were at the back of the engine because of bonnet clearance, so the manifold had a right angle in it.

Wheee!!! I was right when I suggested a Rover! (Even though I thought it was from a 2200 rather than a 2000cc)
