Ive done a bit more web searching and have uncovered some more info about fiat 1242 engines...
1, The 16 valve engine has steel main bearing and big end caps.
2, All 1242 16v and 8 v engines are'nt balanced very well as standard but when they are dynamicaly balanced the standard bottom end is safe till 8500rpm.
3 The 16v head uses hydraulic tappets which cannot be upgraded to solid tappets so this limits the cam choice to "fast road" spec to avoid pump up.
