Hey, so I was recreating the 2.5 Iron Duke Tech IV Engine, and it had a much larger bore than you allow. Yours goes to 100mm and the Iron Duke could be bored to 4" So, just a heads up that you need make it more exciting with more bore! 
We also ran into the same thing with building Windsor V8’s in our development build. So we will up the limit to 102 or 103mm to cover proper 4" bores.
