Diane,

Heres a list of all the engine numbers.

All but the earliest P5/6 engines have the numbers next to the dip stick and start with the compression ratio 9.35/1 and then the engine number itself. you really want an engine with the 9.35 compression ratio.

The most common Range rover 3.9 engine numbers will start with 35D or 36D in the UK there are different numbers for TVR and Morgan versions but they tend to go for silly money.

There were no 3.9 SD1 engines.
