The inlet and carb faces were parallel.I used an 1 1/8" but don't know what it was originally fitted to.I did grind out the ports inside as much as possible before welding on the SU flange.
I remember the updraught manifold is quite a small bore especially the vertical bit.That's why I wouldn't go the 90 degree adapter way.
The box saloon was good for a genuine 60 on the flat,throttle tempered by the original 1 5/16" crank.
Just remembered I'd found an incomplete pair of early sprite/midget twin carbs which the adapter was cut from.
