126 Camshaft

[Rusty's Uncle]

  I am just about to start putting together a 499ccs Fiat 500 engine which I have got totaly stripped at the moment. I would like to try a 126 camshaft from a 652ccs engine as part of the rebuild so anything considered , camshaft , engine , bit of engine as long as the cam ain't rusted or busted  [-/

just look there for the timing of the different camshafts :

you see, that there are little differences in timing...

but I think, you will probably have to adjust the carburettor-idles al little bit.
