@GreenPump Thanks! I have referenced that chart for a few other bolts that were not clear in manual, so that's my plan, but was hoping to find those specific bolts/instruction in a manual that shows the A343F/2LTE combo. Not sure I'm going to.

@GTSSportCoupe Oh man, no, that would be bad! I rebuilt the 2LTE using the correct engine manuals (see screenshot below for files as saved on my computer) - I think I got them from same links you posted in your reply. I labored over every step/detail and torque spec in the RM520E manual. I also gave machinist who did my engine machining the RM520E manual, and we talked through bearing clearances, piston protrusion, ring end gap, etc. during machining stage - everything he machined was done per the FSM. When I built up new turbo, I referenced the RM582E. In my post above, I was just saying I was looking in RM183e (understand it's the chassis & body manual for 70 series) to see if it had info about bolting up the automatic transmission and torque converter (that info is not in 520E), but it's not clear on that part because it doesn't specifically reference A343F/2LTE setup in the AT section.

I've read many of your posts - both you and GreenPump - and have learned a lot through reading on this forum and talking with folks on here. Thank you both for being a wealth of knowledge and so hopeful!

Ah, okay, thats great!!

I'm glad you found old posts which were helpful; you're welcome.
 
Considering Iowa temperatures (will likely be in teens or twenties Fahrenheit when I get this running), I'm considering using T4 10w30 for break-in oil (first 500 miles), then change oil and continue to run the 10w30 through the cold months. My initial start will be in a heated shop, so probably 45+* Fahrenheit. I'll switch to T4 15w40 in summer (around June).

Any thoughts around using T4 10w30 for break-in oil in cold climate? I won't start truck if temperature is below 0* Fahrenheit with the 10w30.

Thanks!
