02 Boxster S 3.2 motor

[DaveBBOXSTER]

I HAVE A PROBLEM WITH Boxster ENGINE NUMBERS. Car documents say engine code is;
M962265Y08601-10 as does the service book plus V5. It's a UK 2000 Boxster 2.7 BUT...The number stamped on the engine says; M96/2167110632 - Based on the fact that the service record shows no replacement engine and the code is badly stamped on the engine does anyone please know what is in my car? I had decoded it as a 3.2 2001 series 7...
