All 3D models are created at 1:1 scale. The drawings which are made from these models can be at whatever scale you set your software for, but the drawings will still show the full scale dimensions.

Well I think that you should scale the 3D models let say 1:2 or 2:1 and then to produce 2D drawings in this case the dimensions will be OK.

I assume that you include the fasteners to facilitate the assemblies, while builders will likely use commercial nuts and screws. As with other British or metric plans, for me it would be easier to substitute UN threaded fasteners.

Yes, exactly to facilitate the assemblies. Later on in the build I will correct the studs as mentioned by Jasonb and try to find out some pictures or drawings of the actual engine to put correct details.
