727 BB and SB output shaft splines the same so a small block driveshaft to work in BB 727?

[Reliabilityman]

Are Big Block and smallblock output shaft splines the same. I am looking on using a drive shaft from a small block 727 for a BB 727 and wanted to make sure there wasnt anything different in splines so that the small block driveshaft will work with the BB transmission?

From 727 to 727 should be the same.
