On the subject of SUs, I’ve used them over the years, but the last three cars I’ve rebuilt, I use a low compression head and the standard jetted 26va Zenith and like the different grades of petrol, I haven’t noticed much difference in performance or economy, though I do crack on, in and Austin Seven way and keeping things simple has proved to be the way forward....well in my case anyway!
