Well, it was quite a delicate situation Craigy as said chap had a substantial amount of my money for another engine, £4,000 to be exact, paid up front (never ever will I do that again, too much trust). Needless to say once I found the issues with the shells I didn't feel that my money was being as wisely spent as I had previously thought, I have now retrieved the parts I have paid for I am still awaiting confirmation of the costs of said parts and the refund I will be receiving as the engine hasn't been built.
