I have a couple spare open 4.08s just sitting in the garage, so I figured I'd try to weld it up and see what happens. can't hurt, right? :)
The problem is limited track/testing time on my budget. Had I known I was going to go 3 sec/lap slower with the 4.6 rear diff, I wouldn't have spent the money on it. Hoping to not make that mistake again!
