Awright, so I'm getting the Ally fitted to the back of the Cummins using a Dodge-to-SAE #3 adapter (keeps stuff much shorter than the OE Cummins SAE #3 housing). My question is spacing: On a typical DMax install, if the converter is fully seated into the pump, what is the spacing between the bosses on the converter and the flexplate? Also, any idea what the tolerance is for this?

Anything more than 1/8 " gets iffy as the converter gets pulled too far out of the pump drive gear. Don't go below .100 as you will need some leway for the flex plate movement back and forth and if too tight the pump drive gear will begin to machine down the pump wear plate.
No. The tolerance should be .100 to .125 max. My rule of thumb is if I have 1/8" gap between the converter lugs and flex plate, with converter seated, I am good to go. A slight variance is ok.
I don't think there will be a big difference between -10/-12. Make sure you use some kind of a heat exchanger pre oil to air cooler as there is no airflow below 35 mph and the oil to air cannot handle the heat by itself.
Well, -10 AN fittings can narrow down to 1/2" ID in some cases. That won't be an issue?
You're full of all kinds of good news. The late 90's 454 radiator I'm running doesn't have large cooler ports like a DMax radiator. The exchanger in the "cool" tank was used for the engine oil in the stock 454 app, and is only maybe 1/2" ID or so. So, that means I need an external liquid-liquid heat exchanger :doh:
