I don't know which SU setup you used (and I am not familiar with the
European 1.5 inch ones), but the Mk3 setup uses a vacuum advance whereas
the ZS carb setup and its distributor use a vacuum retard setup.
Obviously there needs to be some adjustments done to make such a swap.
In my cars, I simply used a dizzy that was designed for the Mk3 when I
put that setup on a 1500 engine.

Subject: Spitfire distributor
After reading Classic Morotsports article about distributors, I started
wondering.
On my 1980 Spitfire I changed from a Stromberg carb to dual SUs. I
think the
vacuum line for the Stromberg must have come off the manifold. The SU
manifold does not have a place to hook up a vaccum line but the carbs
do.
Should I hook up the vacuum line on the distributor to the carb or
should I
just block it off? Or perhaps what I really need to do is get a
different
distributor?
Any suggestions or thoughts?
Thanks
Roger Elliott
