how strong is a 8 1/4 rear end
what is the most hp that you can have will still using a 8 1/4 rear end. Are there performance parts for a 8 1/4 that can handle lets say 450 hp.

What is the axle in?
I wouldn't put more than 300 to an 8.25 rear axle. You can get spools, lockers, posi units, upgraded axle shafts for them, but you would be better off to install a 9 in rear, 8.75 rear, 9.25 rear or a D60 rear axle

correct. I had an 8.25 in the back of my 01 dakota and I pulled it out because the bearing were toaste after 62,000 miles. I swapped in a 9.25 out of a durango R/T and never worried about it.

depends somewhat on the spline count. if its a 19 spline then I wouldn't put much more than 400 to it without upgading the axle shafts, carrier, R+P and bearings. If its got the 29 spline shafts (i think) then i wouldn't worry about it unlesss your building a strong motor.
I have seen a lot of weaker, small axles live under huge tires and/or lots of power. Then again, the people driving them were not beating on them. I've also seen guys tear apart the R+P Iin a D60 with a set of 35s and a stock V8 in a truck.
It all depends on how your going to be driving it. If you take it easy and just like to cruise (maybe hammer down once in a blue moon), then you shouldn't have a problem. If you like to take it to the strip every month or more, then spend the extra money in building an axle that is designed to take it.
