Bone stock with 100,000+ miles? Probably not. With nice axles, and good gears, and a rear end girdle, asbsolutely. Those are A LOT tougher than guys give em credit for.
A funny story. I had 2 buddies years ago, both with 8.5 inch 10 bolts, decent gears, stock axles, new bearings, etc, with 100's of passes on em each. Both cars ran mid to low 11's, with 406 sbc's. Both guys at the same time, built new 9 inch fords because they were worried the 10 bolts were on borrowed time. Same mods, gears, re-build, bearings, seals, etc. Both guys broke their new 9 inches on the same 1st weekend out, no kidding.
