Correct. The engine shown is a Fiat 850 843cc type engine block, with a Fiat 850 (or 127/A112) cylinder head, Fiat 850 carburetor (Weber 30DIC), Fiat 850 903cc type alloy oil pan, Fiat 127/early A112 intake manifold & an aftermarket Triger/Abarth cogged drive-belt kit (replaces timing chain/gears & cover).
#4146347 is one of the Fiat 850 part numbers for the 843cc engine block, though the actual casting number (cast into the exhaust side of the engine) is often different by a few numbers.
The only thing I see remotely related to an Abarth 750 engine (or the year 1958) would be the Fiat 600/D coolant outlet pipe seen on the top/right corner of the engine, though the Abarth 750 unit often had a temp sensor installed (for the temp gauge).
So Lescol, what's the
real story on this?
4,000Euros is a hefty price for a Fiat 850 engine!
