Porsche 616/12 Engine for 356B 1600S — Complete, Period-Correct, Rebuilt

A highly sought-after Porsche Type 616/12 1.6L flat-four engine originally built for the 1963 Porsche 356B 1600S. Case stamping P☆704285☆ confirms factory-correct identity. Rebuilt approx. 4–5 years ago, then cosmetically refreshed with powder-coated tins and factory-style decalwork. An exceptional candidate for a correct restoration or high-value numbers-appropriate replacement.
