you don't need the holding capacity of the dana. the dana was used in drag racing because of slicks. you could probably stick a 7 1/4 in there for the turns and you'd be fine.
cons -
cost
weight
ratios
not easy to switch gears
less availability of parts
I know I am just thinking if I am going to dump 2k into redoing an 8.75 I minds well spend 3 and have a brand new bulletproof Dana with disks brakes, powdercoated, ready to rock n' roll. I am on the list for the Passon 5 speed, so i think that with 3.54's in the Dana would be a nice livable on the street choice. This car will be 95% messing around on the street and occasional open track day type deal. I also like the idea of being able to throw slicks/drag radials on it and doing drag racing too. It would be 1 less thing to worry about down the road if I add big power too.
