 After I drove it around a bit to stir the front tank I pumped it out. The results were colorful. I have sloshed a few gallons and pumped it out twice since and it is coming pretty clean now.

Its kinda interesting. I get the impression that it mainly took the cap off of RPM and moved the torqe band up. It starts to pull in a respectable way at about 3000 RPM. Problem is that the truck currently has 3.54 gears in the back. So you dont hit 3000 RPM till you are going about 75. So I really have to fix the gearing to get something out of it. That said I still have the origional 3.73 equipped dana 60 that came out of it. Which should help without makiking it a pain to drive long distances. Long term I really need to do something about the NP 435 transmission. I am sorta conflicted about what the right path is on that front. I could run the NP435 with a gear vendors and 4.30 gears to get 3300/2600 at 75 which would be pretty good. I could also do a C6 with a GV and the same gearing. Or I could do a MDL 10 spline tremec TKO500 backed by 4.56 rear gears.

I found that 265 DEH to be a complete dud in a 428 and I would think it even worse in a 445.  You still need to cam that puppy up IMO.
