There are different options, some are straight and easy (petrol 6 cylinders), some a bit more complicated (v8) but very doable. You should first determine what you expect from the result: Power? Economy? Your budget will also be a determining factor, especially if you're not doing the job yourself. Tell us more on what you want and we will help you. If you were in the US I would recommend you buy a W108 4.5 donor car as they are dirt cheap here and transplant all the mechanical bits in your w111. That's nearly a straight fit.
As you are in the UK and for specific RHD exhaust manifolds and steering box clearance reasons a W108 6 cylinders or 3.5 v8 would be the easiest. The r107 would be also be an ideal donor car for engine and transmission, 6 or 8 cylinders. 500 sl/slc would be the best. a good W126 560 would also be an interesting donor car, but you would need to trace RHD 500 sl/slc exhaust manifolds and downpipes.
