Matching-numbers V8 and correct engine specification for the chassis
The single most important structural check on any Urraco is whether it retains its original, matching-numbers Lamborghini V8 in the correct specification for the chassis (P200 1,994 cc SOHC, P250 2,463 cc SOHC, or P300 2,996 cc DOHC). Cross-engine swaps between P250 and P300 do exist in the market and are a material paperwork item. Cross-check the engine number against the factory build record via the marque registry and, where possible, a Polo Storico heritage confirmation. Watch specifically for a P250 SOHC engine fitted to a chassis originally supplied as a P300 DOHC — the P300's higher market band is anchored on the DOHC engine, not the chassis alone.
