Engine block

From The Broken Fiat Club

The Fiat 500 Abarth engine block is made of cast iron, and has an aluminum bedplate.

Bore: 72mm (2.83 inches) Stroke: 84mm (3.31 inches) Displacement (83.5 cubic inches)

The block includes a forged steel crankshaft and forged steel connecting rods. Pistons include full-floating pins, oil squirters, and a structural aluminum oil pan. [1]

Note that unlike the European version, this means that the American Abarth already has forged internals.
