A friend just sent me this picture of 206 block #0000081. It's interesting to see it doesn't have FIAT cast into the depression to the right of the flange where the engine number is stamped as all the others seem to. He says it has definitely not been ground off as the rough cast surface is still intact (although this is not so clear in the photo). Also the overall block surface finish is considerably rougher than usual. The block photo'd in the 206GT Uso e Manutenzione booklet (p6) is also missing the raised FIAT lettering but is a much smoother casting. Any comments? Image Unavailable, Please Login
well Ferrari did build the original motors for his race cars, perhaps this is one of those. He gave functional motors to FIAT for FIAT to cast and redesign (the redesign was some strengthening to make it streetable). I know the 206 came out after the FIAT 2.0 but most books agree they were designed at the same time. I have said here before that all blocks were cast by FIAT and I stand by that but some prototypes had to be done at Ferrari for them to give FIAT functional motors to work with and cast.
I think you must be right, as the 1967 F2 regulations specified production based engines which must have used the same block. The earlier Dino blocks were quite different.
