Seeking 3.55 Ring & Pinion for an 8 1/4" rear end.

yep, thanks I currently have a the bigger carrier with the 3.23 and I'm struggling between going with the 3.55 or stepping up to either the 3.73 or 3.90...
Its will be behind my 392stroker w/46RH trans, at the moment I'm doing 60'ish at 1700rpm.. lol
*starts chant* 3.91! 3.91! 3.91!
