Tom,
The question you need ask yourself before pursuing this is WHY? One of the
major misconceptions about Webers is that they will immediately provide more
HP than SU's. It is true that in proper tune and at peak rpm some extra HP
is found, but SU's actually provide more torque at low revs and better
pickup for the general road work most of our LBCs get. So if you are
planning to race your Spit, full on and flat out, then Webers are the way to
go - But plan on spending a lot of time on the dyno to get all the jettings
right.
Perhaps a more an satisfactory alternative is to up the size of your SU's?
