Fastest Truck List
If you want to get into the 11's you should just step up your converter. With the power you're making, you could get a triple-disk with a higher stall speed and still keep some street manners. If that doesn't do it, then you could entertain the gear swap.
Another question - do you want to be able to do 11's at the drop of a hat (i.e. street race) or just at the track? Reason I'm asking, you could have some other wheels/tires (i.e. shorter) on tap and use those for race day. You would effectively be changing your gearing, but only temporarily.

I see no EC AWD/4WD SC'd only, on street tires in the 11's.
Yeah basically I want a street trimmed 11 seconds. I could already have gone a lot closer to 11's with weight reduction.
I've pretty much decided to go 4.10's. At least offset the 20" wheels I run around on now. I will put the 16's back on from time to time for track and maybe find some lower profile tires for them. Don't think I'd be able to plant it with 4.56's.

You stated you were looking around for used diffs, and found one for a silvy SS w/4.10s. You wont be able to use that front diff without switching the guts to yours, as there is no front axle actuator on it......just a note...

Wound up going the buy a differential route. Bought a NOS diff yesterday with 4.10's. Still have to come up with a set of gears and install kit for the rear. Between the gears and suspension drop gonna be a fairly big upcoming project.

Yeah, NOS (new old stock) OEM (original equipment manufacturer) front differential.
Little bit concerned about the age. Seals might be a problem? Looks like manufacture date 11/99.
