The good thing is if the tubes are welded and you add the super88 kit, You should be okay.
Tubes have already been welded. Super 88 is on the list, but a cut down front D44 is the next upgrade.

There ya go!
sounds like you have done some research.
I'd check on some chrome moly shafts and some ctm or like joints for the front D44 as they are the weaker point.
I'm also running a front D44 pushing 400 HP LT1 and have put some pretty good beatings to it without failure.
My intentional weak point are my lockouts.
lifetime warranty and only a 10 min. Trail repair.
