Nice find...but isn't that pretty much just an M42 block? I'm no expert, does anyone know the specific differences?
That's a nice little bit of BMW history there. Even if it's broken I'll bet it'd make me a fine coffee table!

I have no idea whether the S42 block is different to the M42. The difference could just be preparation, i.e. the listing says the crank case has been polished.
I expect that the major shared parts such as block and head would have been specially selected for the S42 on the better characteristic such a the bore wall thickness, etc

"The S42 engine was a 2.0L touring car engine with a 86.5mm bore and around a 85mm stroke, which shared the same block as the street going M42. Unlike the common M42, the S42 had a more sophisticated engine management system, and had individual throttle bodies. The S42 unfortunately did not share the same valvetrain as the M42, and is a solid lifter valvetrain (possibily from the S50Euro) fully capable of over 9000rpm, but was limited to a 8500rpm redline, as dictated by touring car rules. It was mounted upright in the bay, not slanted, and ran on a full dry sump oiling system. The pistons had a static compression ratio of around 12:1, and running on pump gas, the S42 made around 280hp (and up to around 310hp later in it's life). Good luck finding more information on the internet about the S42, it's next to impossible.
Oh, and no, the S42 cams will not fit"
