I just swapped a built 400 SBC into my XJ. Is the 8.25 going to hang in there for the foreseeable future? I can find all the specs I want online, but I am looking for personal experience. Thanks Jeepers!
Its the 400 small block, it came out in the 70s but its a great tourqey motor!
Sounds like my kinda build!! Could you post pics of the engine bay? And I guess if you're questioning its strength have a junkyard Dana 44 on deck I guess? Don't know a whole lot about axle durability yet
Depends on how much you put it through. The 8.25 is strong but it does have a limit. I would keep it in until it does crap out. But till then I would prepare and get another axle to swap in. Maybe a 9" or 10.25/10.5.

It'll be fine. They put it under 3/4 ton vans with 360s. Hell, I own one. It's a stout axle
Street use I couldn't agree more. Particularly if you've got the 29 spline, but I doubt the 27 would have any problems. If you're running big tires and off-roading, go with the "run it till it breaks and replace with an 8.8" response.
I had a 27 spline for the longest time with 36" bias swampers with beadlocks. Ask anyone that knows me and they'll tell you I never wheel light. Never had an issue. Don't drive like an a-hole and it'll be fine.
They speak of my drinking, but they never consider my thirst

I can post more pictures is one so desires.
Its a really fun rig that I use for "dual-sport". But now with the new motor I am desperately trying to pass emissions haha
