Bank 1 = side with cylinder 1. On the LS engines (L77), it is the left hand side of the engine, which counter-intuitively is the right hand side when you look at it with the bonnet up. (AKA passenger's side)

Another way to look at it is that bank 1 contains cylinder 1 while bank 2 contains cylinder 2.
Cylinders are numbers front to back as if you had folded a V8 into an inline 8 configuration.

Further more, if you look carefully at the engine block, you’ll notice that bank 1 is further towards the front of the block than bank 2. That’s because of how the conrods connect to the crank :p

So there is no need to get confused between driver side, passenger side, RHD or LHD depending on which country web site you look at…
