Engine code EXP 250

[Ginger Bob]

I do have a question if anyone on here can help please
I have to strip the engine down over winter due to ongoing issues, but in the meantime I have bought another engine that I'm keen to rebuild, and maybe use as a replacement,
My original engine is from a Rover sd1
My newly purchased engine is harder to find out what it actually is the engine code is EXP 250
All I can find out is that it could be an experimental engine hence the EXP and I believe the 250 is just a rolling over number system used at factory, I believe it's an experimental engine and could be a blueprinted prototype used on a test bed or in a press release car or special vehicle, can anyone add any more information please it would be greatly appreciated to know more before I strip it down, many thanks in advance Bob
