TECH: 6 Lug 14 Bolt SF into an Avalanche

Here's a few pics when I brought it home. It's currently in the rear of my truck geared with 4.30's and a rebuilt Power-Lok differential much like GM's "G80" Gov-Lock or Ford's Traction-Lok . It's a good little axle but I fear for it now looking at the specs of my motor swap. Iron block 5.3L bored to 5.7L, conservatively guessing the output to be no less than 350hp and 375lb-ft of torque with a 4L60E and NP241 t-case with 2.73:1 4LO. 325/70R17 Nitto Terra Grappler tires for the street and winter and 35" BFGoodrich KM2 Mud Terrain's for the trails. If the rear Dana 44 takes a **** on me I'll either replace the shafts with forged pieces, or do the SF 14b 6 lug swap like you are. BTW, the front is also a Dana 44, 6 lug, all the same as the rear so I can still rotate tires. Nothing custom or one-off, I took these axles from vehicles in the junkyard and there are plenty more.

I'm positive. It's a Dana Spicer 44 rear end, 6x5.5" (6x139.7mm) bolt pattern, 8.5" ring gear, 30 spline axle shafts....your typical D44.

What did those axles come out of?
UPDATE: The rebuild parts have been ordered for the 14 bolt, and the plan is to get an avalanche housing to my fabricator so he can build a jig, and I will be assembling the differential.

The 1500 Avalanche has always used the 10 Bolt axle and 5 link suspension, as far as I know even the new ones still use the 10 bolt and 5 link. The 2500 Avalanches (while they were made) had the 14 Bolt but, it was hung on leafs springs and was never available with the 5 link.
Now, the Avalanche's Paris Hilton wanna be sister the Cadilac Excalade DOES use the 14 Bolt SF hung on the 5 link suspension with the 6.0L Motor option.

Are they interchangeable with the older 10 bolt AV setup? i.e. identical suspension/bracketry? Haven't seen a 6.0L on any lot up here. I don't think anything with any V8 is too popular here right now.
