The S847F says it was made at the S=Sterling Plant and the 847F is the application code for the type of Ford it was used on and how much the axle can hold.
It is also a 3.55:1 ratio limited slip 8.8" rear end.
Your date code is not right at it says it was made on the 21st day of the 14th month of 1994.

Second part is the axle ratio: There should be a "3L" preceding the 55 if it's a Limited Slip. If it's open, it would just say '355' .
4th is the ring gear diameter, in your case an 8.8 inch.
5,6,and 7 are the build year, month, and day, in this case, August 6th, of '99. (9=1999, H=8th month [and there is no 'I' in the sequence]) and '06' is the 6th.

I was wondering the same thing, cool to know I have a limited slip and not open.
I thought it was just low on power, but since my truck's been at the tranny shop this week and I'm driving my dads '00 Jimmy, that makes my truck feel like a sports car!
