Are they usable in high performance applications at all? I would think the LX and truck guys arent swapping in 727s in their cars

The LX car NAG1 seems stout to around the 1000hp mark but much beyond that they seem to go th400. The truck trans are decent to about 500hp but overall they suck. PCS just came out with standalone NAG1 ecu. The only reason you don't see more nag1 swaps is because of lack of controllers.
Mopar to the bone!!!

The NAG1 (New Automatic Gearbox Generation 1)
I assume someone make a different output shaft so you can get rid of of the rubber coupler and can go to a slip yoke... what does that nagy weigh

I've built them both and wouldn't use either in a race application because of the gear ratio's, converter choices, parasitic drag and/or weight. Street use is fine.
The 545 comes in with a dry weight of a 175lbs and the 722.6 right around the same weight as a 727.
I run a 545 in my truck and rebuild it every 100 passes or if and when the clutches burn up before that.

The 518 weighs a big 147.. what a 727.. its got to be right at a 100 lbs or a bit more... I know the OD and tail shaft assembly feel pretty heavy

I figured if the trans is any good that someone would have built a output shaft and a tail shaft for it to utilize a slip yoke.. but looking at the 2 WD there isnt a bolting point at the rear so I guess it would have to be the AWD version
