If you get a chance to pick up a Haynes Manual - Alfa Sud/sprint
1974 - 1988.
get it.
It has a supplement section with info on engine codes for sprints (same as series 1 33). Lots of dual carby 32 / 36 webber and delloto info.... no 40's.
Maybe not accurate for series 2 33 and up.

If it helps... try Ebay.

GOod for S1 33s.
