Yeah the 44 is marginal, I dont do a lot of low range crawling, and added a finned cooler w more capacity right away so maybe thats part of the reason Ive been ok- maybe I just got lucky(knocking on wood) , A super 44 would be the min they should have used, but still ...
Have you ever put a different rear end in one?
You are dead nuts on about performance parity - I have to explain this all the time to people, and its one of the reasons Im still ok with a 16 year old truck - its performance is on par with all but the very biggest new stuff. The power has to be in the 4 Valve head.
What do you charge for labor on a manifold change?
best sir !

I've looked into putting a Dana 60 in one, But couldn't get anyone to make custom axles with the ABS reluctor flanges. Strange sells new bare Dana 60 center sections. The plan was to use the Nissan Dana 44 axle tubes inside some cut down Dana 60 axle tubes & machine some adaptor rings/sleeves & weld the D44 axle tubes in at 2 places each.
Probably be cheaper to use a used D60 out of a 2500/3500 Express/Savana or a Econoline 250/350, But the Axle/ABS issue put a halt to the project.
Servicing the differential probably helps a lot, The ones I see have 120-180K miles & have never been serviced. The oil comes out looking like Metallic Silver Paint
I charge $400 labor per side on the Manifold/Converters, And charge $400 to weld both up on the vehicle.....Which I've been quite successful doing. They usually blow a small chunk out on each side with a couple small spider cracks. After I get the heat shields off, I plug both upstream O2 sensors, Start the engine & run it at 2000RPM for a few minutes to preheat the manifolds, Run a stainless brush over the area.....Then MIG weld them.
