Technically the Core stage should have a LR105 variant powering it, but no high powered LR105 variant exists in BDB currently. The H-1D center engine is thus utilized to overcome the issues with scaling down the rocket (otherwise it would have been more efficent to make a single stage.)

Zorg has discovered the same issue with the Atlas II family. So while IRL the Atlas II should fly with the RS56 OSB and OSA engines or whatever they are designated. I suggested an H-1D to overcome the differences of scale.
