Hi,

Newbie here, I have some questions about my Fiat 850 coupe (series 1 - 1965).

It looks like the engine has been changed from the original at some point in its history. The current bottom end/block has the same model number (100GC000) so it is the same type. However the cylinder head from what I can gather is from an A112 Abarth 70HP.

I'm just wondering if anyone knows if this represents an issue for instance:

Is this a good/bad thing i.e. good upgrade or not?

Should this give more power?

I'm running the standard DIC1 carburettor, does this need to be changed for the Abarth one for optimum performance?

Anyone else running a similar setup?

Many Thanks.
