Could Edelbrock cast a flathead block

[flatheadmurre]

First making the mold and cores with correct sizes and taking into equation that it will shrink when cooling....
Then its correct material quality and pooring it without to much rejects.
Not an easy job believe me !
Its much easier to cast aluminum then cast iron.
Making core boxes and stuff is needed for a descent cost if going for even low series.
3D printing is for small stuff and one of.

One of....Ill agree with that for any production runs then suitable tooling should be produced.
But I will argue that 3d printing is NOT only for small stuff... and that aluminum does not necessarily make things easier. Sometimes it wil open up a whole nuther can of worms....
