I had a Rolt built 3 bearing Engine in a Speedex a few years ago. ( My father ran it in a 33 Box for a while )
It was completely standard in appearance but it had the centre mains Line Bored in the case with the block bolted down in my memory is correct. ( My Father had the work done in the 1970s /1980s ) It was not a Reliant Crank Conversion.
So I think that there is no single formula for his engines they were done to customers requirements.
