Strong, compact, and not too heavy.

The gearboxes on the 2000 (SRL 311) and 240 series had a lot of commonality.
IMHO there is nothing wrong with the MG box with OD (unless you can't find
one)

The 1950 size isn't usually a problem.
Larger than that sure can be. The factory had poor control of castings and
core shift can result in walls that are way too thin, overheating, and in
extreme cases, actual perforation of the cylinder wall while in service.
Boring out even further and then installing liners is safer if you must go
much over 1950.
As a vintage racer, I would of course have no _practical_ experience of
larger than stock bore sizes......
