I think there's someone selling one for $$$$; they have a web page
even (I don't remember the address though).

Aaron Johnson posted in response to the list with a good report
on a pair of HS8's (2").
Note that our lumps don't turn as many RPM as the B's, though the
overall max airflow willbe a little higher on the '6 if the engines are in
similar levels of tune. 1.75" SU's are probably fine for a fairly stock or
mildly modified TR6, though they may start gasping above 4500-5000 RPM (like
the Zenith's). 2" SU's should be good enough even for fairly extreme levels
of tuning on a '6, though they'll give up a little to a sidedraft Weber at
the top end of a modified engine. Not much, though, and they're much easier
to deal with (also, the tri-weber will suffer at low/mid rpm from the
uneven-intake-pulse problem).
