[GTA Alfa]

My question is this, after Alfa Romeo went through the trouble and research & development of the Spica system why didn't they offer it in other markets?

Cost.

There are claims that the Spica pumps cost was the same cost as the engine itself and that carburetors were more cost effective and budget friendlier than Spica.

They did offer variations on the Montreal and other models, but not on the production twin cam engine outside of the USA.

Canada also recieved Spica cars like the US. Only difference was that between 1969 to 1971, the Canadian market had both Carbureted and Spica versions of each model. Then from 1972 to 1981 you can only get Spica.
