I personally won't be casting these, I have never cast anything, never even attempted it, wouldn't know where to start. This was just a one off for a build but if someone who does good resin casting is interested in doing them then maybe we can get something to happen. I could do a 4bt pretty easily based on this engine. There is still a lot of work to get these up to scratch as the 3d printing leaves a rough surface and the block still needs some detail work to make it more accurate. I have also done a 24V rocker cover to suit just for a bit of difference.
