I know Tony has patterns, but things have moved on with respect to one off castings from the days of timber patterns and the moulders skill.
You can now scan items in 3D, using a CAD package scale for shrinkage, put machining allowances on etc, and 3d print patterns for a fraction of the cost of paying a patternmaker/carpenter to make them. Often the way to go with one offs is to print a poly pattern which effectively melts as you pour in the metal.
My mate Ken had had this cylinder block cast fairly recently (in iron), I think the picture shows the size well, but does not show its complexity. I hope the link works

Whilst I dont disagree with any of Tonys costings for supply of castings, or machining, or indeed the prices he is quoting for blocks etc. However some of the other figures knocking about regards to pattern making seem a little far fetched to me, particularly given the advances in the industry in the last 10 years. Remember my other hobby involves having replacement parts manufactured when the existing ones break or wear out. Old spares and off the shelf isn't an option.
Its always struck me that the heritage industry is often taken for a ride pricewise. Particularly the vintage car world.
