I once had a 1380 with 266 cam and I believe we ran 34mm chokes (but it was a
while ago
so my memory is fuzzy). With a full race 1293cc motor I have used up to 40mm
chokes, but
these chokes in a dcoe45 are not optimal (better to go to a 48mm weber). I went
back to
38mm simply because the venturi effect of the 40 chokes is low enough that
getting accurate
jetting was a nightmare (too much variability)
Having said that, the 266 doesn't really want to rev that much over 6000 anyhow
(6500 IIRC)

I have some custom radii machined out of a block of alloy. I might try and get
a photo and scan it.
On my other car, I have a cold air box made up for which the radii are
integrated into the
mounting plate (machined out of a block of alloy too).
I have used the 50mm weber ram tubes in the past and have also used a K&N filter
housing with integrated radii (made by HP products - the same guy that makes
that awesome
supercharger kit)
