Put the engine on eBay and offer postage. use Speedshift or similar to book a pallet courier - buy 2 dirt cheap ratchet straps from tool station to seucre the engine to the pallet, charge £75 for delivery. If it is a complete engine and you offer postage £500 should see it gone in a week or two.
You can do similar for the G/B and T/B - I sold mine cheaply to a local chap just cus i needed it gone, still got £100 cash for it - i believe you can get nearer £250 though.
