The same heatsinks the same tonnage and the same slots. So there is a bug 175 and 275 need to weight 0.5 tonns less then the 180/280 versions.
Correction: STD 275 to 280 there is the 0.5 difference, the other engine versions dont have these!
On this engine you can see its a bug, the others are wrong in the scaling.
