It should work fine, you just need the adapter from the T19 to the D300. If you're really going with the D70 and D80 combo, I would go with the 351 for the added torque. I've got the 302/NP435/D300 and its got plenty of pep but I'm not running monster axles or tires.
What axle ratio and tire size are you looking at getting?

One thing you're going to find with that size front axle is that the engine is going to have to sit higher so that you have room between the axle housing and oil pan. Any reason you're using the T-19 and not the T-18?
Yeah sorry guys. Probably 5.13s or 4.88s.. i want 38s but i wanted the t19 because im not really one for a useless first gear being that the.jeep will be on the road half the.time.. the granny gear will only get you to what..8 mph? Lol. I need a set of useful gears ..and i need to meet highway speeds maybe once a month
That much power, that strong of axle, and you are not going to wheel it? I would think that you would want the granny low! Granted, it is a useless gear for normal driving, but final ratio is still 1:1, so just think of it as a 3 speed. That granny would make for a nice easy crawl speed in low range, and I have no problems DD mine with the T150. It even made the 10 hour trip to Chattanooga and back last month at 65MPH avg speed...

T18 and T19 both have a 4-1 ratio unit.
The T19 had a 6-1 in Scouts 5-1 and 4-1 in Fords 80's trucks and Bronco's
The T18 4-1 was way more common than the 6-1.
The 435 is good unit also.
Read the Novak site for lots of info on these trany's.
The T19 is fully syncro! thats what makes it so usable!
