Does anybody know the specs for the different original cams that have been used by Fiat in their sohc engines?

Are the cams interchangeable between different engines (1100, 1300, 1500, 1600) from different years?

Yes the are changable. The old carb engines often have a 272‚° camshaft (1.5 carb, 1.3 carb etc.). The ritmo/uno 1.5 mpi engine has a 244‚° camshaft.
All other camshaft from Fiat have less degree's, as far as I know.
