If the engine is not yet installed in the vehicle, check behind the timing cover or on the rear of the block behind the flywheel for "010" (1% added tin) or "020" (2% added nickel), or both. The numbers are big and easily noticed.

There's another thread going on here somewhere debating the benefit of having a harder block (extra nickel).
