The .63 will come in at 3500 RPM I guess. The .48 around 2500/3000 RPM.
You can't go wrong with any of the three housings but I would go for a .63, if you consider to go over +350 hp and top speed, the punch will press you back into the seat like fukk.

For less than 350 hp the .48/.55 will do the job better.
