Default The New 635HB Speed & Torque

Mike,

I understand that the 635HB is the recommended replacement for the HS-605 BB. The 605BB was 77 in.oz. at .16 sec./ 60 deg. The new 635HB is only 69 in.oz. at .18 sec. / 60 deg. I am interested in your commentary on the shift in performance specifications. Was this necessary in order to achieve some new characteristic for the 635HB?
