Loved the SU's, especially the sound they made when you put you foot down. BUT, they are a pig to keep balanced (mind you I was pretty old school and did it by ear with a bit of hose), and they required a hole through the fire wall to fit! Still don't know how that past engineering at the time. It was all boxed in and welded up, but seems a bit dodgy.
They ended up getting removed when I got the engine reco'ed. The new engine mounts sat everything up just a bit higher so when you started the engine and at rough idle, you could hear the top of the fuel bowl knocking on the firewall.
Should have persisted on a fix, but was really over it at the time and I needed the car, so I and got the mechanic to fit a Stromburg. It was never the same
