Thanks for the info Jerry.

I have done a small amount of work on the engine but as all the dimensions are massively out it really isn’t worth trying to make parts in a scale size so parts have been made to look something like just like the rest of the engine, there has also been a large amount of filling done as there are more holes in the mould than the government’s half arsed levy on bankers bonuses, there is still a lot more to do including the pipework to the radiators
