What chassis are you planning on putting that engine in? A factory front sump won't fit in an E36. There are custom oil pans sold specifically for E36 M62 fitment sold by Cybul and Adamat

Into a car that was originally front sump (E30, E34, E24, etc...) the factory M62 RWD oil pan can be made to work or, in the case of the E30, work with very minimal modifications.

I'm not trying to sell you my dry sump - just trying to steer you in the right direction
All M60/M62 engines are front sump. E39's actually had models with rear sump (all I6 models) and front sump (all V8 models). They have completely different subframes, suspensions and steering assemblies (V8's use a steering box, I6's use a rack) to account for this. This is part of why my next swap is probably going to be an N62 E39 - I want the lighter aluminum I6 subframe and better suspension along with a steering rack - but with the V8 power. The E39 V8 subframes are steel, the steering box sacrifices a lot of feel.

The E53 was able to use a V8 with the steering rack because of how deep the engine sat in the bay relative to the firewall (and because it was designed for a V8 with a rack from the get-go). Z8 also uses a rack but it was designed for use as a V8 from the get-go. It also has a unique oil pan - it is very possible it is the "missing link" in that it's factory oil pan may allow fitment into a rear sump subframe. But my friend who bought one has yet to test it...
