[Healeys] Weber vs SU on a 3 carb Healey

[Oudesluys]

For outright performance and looks go Weber or better still DellOrto. 
They are way better than the SU's, much more stable, especially the 
DellOrto's and offer a far superior response. Also there is little that 
can wear apart from some small O-rings and the membrane of the 
accelerator pump. The butterfly spindle runs in ball bearings. The 
widely available 40mm should do but do get the chokes and jetting right 
which will be the biggest challenge. The best results will be had with a 
faster cam and a higher compression ratio and you may have to experiment 
with the ignition advance curve. Once properly set up the system will be 
hard to beat, even by fuel injection.
Read the  book  "How to build & power tune WEBER & DELLORTO CCOE & DHLA 
Carburettors" by Des Hamill, ISBN: 1-901295-64-8; UPC: 36847-00164-3, 
first though.
