The problem is with the warranty issue. There are several ways this IFS diff could be "beefed up", but they all would void the warranty.

I'm hoping that I can use the 8" ring and pinion in a 4.56:1 ratio and be under the factory warranty (that way I don't need to mess with the rear gearing). I'll beef the whole thing up, once it is no longer covered by the factory (easy for the rear). I also need to upgrade to the new front drive (prop) shaft that has the 30% stronger wall strength. I have already destroyed two of the stock ones. Does anybody know if they use a bigger U joint on the new one?

EDIT: I understand they had to rearrange things under the 3 to fit the new V8 in. That might change the length of the new drive shaft that comes with it. Even if I could get the 8" gear for the new axle, it might be difficult to get the factory drive shaft to line up. I remain optimistic though. It seems it would be easier to just use bigger (stronger) gear all around and not worry about the warranty deal.
