Tell me about a 9 1/4 Dana

I'd take an 8.75 any day over a 9.25.... Yeah the 9.25 has a bigger ring gear but between the axle bearings wearing directly on the axle shafts, the S/G units that were prone to failure in the 70's & still prone to failing in the 2000 time frame.... No thanks...

The 8.75 has been known to live in plenty of 10-11 second A bodies... Thumper has run in the 9's for years with his 8.75...

If you want to swap gears on a 9.25 it requires setting up the gear mesh... On an 8.75 you swap the center section... In the past I had a set of 4.30's a set of 3.91's a set of 3.23's & a set of 2.76's... 45 minutes & your ready for a Friday night race, then another 45 minutes & your ready for a 500 mile road trip..
