Have to agree with Dozer, I wouldnt be without triples (SU's suck!) but Dellorto 40DHLAs make a good road setup, seem to suit the car at least as well as Webers/Mikunis (I've had all three!) secret is to ignore all the experts and do a few dyno runs, I ended up using emulsion tubes in my Dellortos that the experts had rubbished (read"had not thought of")
