those SU carbs should never have been on any aircraft engine, they were bad enough on auto(im)mobiles.
Agreed!
I have a few friends who owned Torana GTR-XU1s years ago and without exceptions they hated the triple SU`s the car came with.
One or two went out and refitted the engine with Webbers. Back then it was not an inexpensive excercise but they considered it worthwhile!
(Slight thread drift follows)
Drove an XU1 once. Was not impressed! Preferred another Friends XB GT Falcon which had an engine worked more than the `standard` GTHO Phase 3.
