8.25 8 1/4 Rebuild and modification

As RRR commented, I am a believer in the 8.25" rear for STREET/STRIP use, especially with pump gas and no transbrake use. The bearings and axles seem equivalent or superior to say, 12-bolt Chevy stuff, and you know they get raced. The ones who use C-clip eliminators on the Chevys, we would upgrade to an 8.75 or Dana 60 by that stage. I made hundreds of runs at the 12.50 level with a 360 (400hp?) and over a hundred with a 416 running low 11's, with slicks. No transbrake and a 904 wide-ratio trans. I even was running the small (gasp!!) 7260 U-joints, with zero failures. Up to 500hp (flywheel) and under 3500# I think it's fine for general purpose use. MoPar's camshaft test mule was a mid '70s Duster with a 4.30 geared 8.25 and they were using a low compression 400 BB running 10's eventually.
