How's that NV3500 holding up? I swapped a 6.0L in front of mine at 150k miles and was always afraid of it giving up, never did though. With the stout pressure plate I had on it, it kept breaking slave cylinders, cracking the housings! Had any trouble with that? I think I put 5 or 6 slaves in before I went to a t400. I just remember with 3.42's it would go from 25-115 in 3rd!
