I was wondering the same thing.
some of the research I have done leads me to believe this is quite a complicated process. The HP70 ans HP95 are different as far as physical size and the Hawk has a different mounting system than the SRT.
so you would need all of the hardware that attaches the 95 to the frame a different driveshaft and a new rear end which has more traction related “bars” than an SRT. I say this because it sounds like you want to make Hawk power in your SRT and engine setup using an HP95 would surely have over 800 to the wheels and that kind of power would shred the SRT drive train.
you would also need a replacement transfer case front drive shaft and higher strength output shafts from both differentials, assuming you are going to keep it AWD
Stock SRT parts cannot handle a Trackhawk level of performance, for very long,
I made the mistake of thinking I could transform my SRT into a Trackhawk killer which is possible but it would have been better money spent buying a Trackhawk instead of the SRT.
it can be done but it will cost you.
I would guess you could get it done between 25k and 30k with the parts and labor and if you are going to build, let’s say a blown 426, you are looking at another 30k. Those are the numbers I keep coming up with.
now before the haters jump in and tell me I am crazy we all know a guy that knows a guy who could do it cheaper but I am talking about a real professional shop for both that would give you real reliability and drive ability which Bubba can’t do.

Not sure about 8hp95 compatibility, but at least there is a supposed upgrade to the clutch packs from Raybestos (I say supposed because I don't know anyone who actually tried it). It's called GPZ FRICTION CLUTCH PACK. They claim it can handle more power and exceeds OE specifications.
New Transfer Case. Front Differential is the same as in the TH.
Keeping HP and TQ @ the same as Stock TH levels.
Have @40Gs into her already at this point
Unfortunately, Trackhawks are in high demand from thefts, new one stolen each day

The HP70 has a torque rating if 700nm or around 520foot pounds. I read about guys that have a little more than 600ftlbs on the stock HP70 and ar3 doing fine but don’t know how they drive.
maybe In time some mor3 common clutch packs will start to be available for thr SRT. I would get a set installed as I’m over the factory rating now but mine is just a weekend warrior during good weather and sits most of the year. Im not a track guy. I might put 2k on it this year.
good luck and if you find something that works please let us know.
