8.25 rear pros

Thou the 8 1/4" is capable, I believe the increased use of it is mainly because the 8 3/4" is getting harder to find and has the smaller bolt pattern, 5 on 4" instead of the more common 5 on 4 1/2". Yes it will handle a fair amount of HP, keep in mind the ring gear is only 8.25 in diameter. The axles are 27 spline and are kinda puny. Yes they will handle most street cars that are daily drivers. And if used with that in mind they will fill the bill. I have a 3.21 SG 8 1/4" under my 360 69 Dart for the last 12 years and have not had a single problem. If you plan on bolting slicks on your car and plan on 1.30 60 ft'ers than this is not the rear end for you. All this is MY opinion, I'n sure some will not agree.
