There is no such thing as a bulletproof 727 , put enough power to even the best built unit with all the expensive parts and you can still turn it into a pile of scrap . I just built one for a 650ish HP engine , but it's not the HP its the TORQUE that will hurt it , it wasn't cheap and I didn't go all out . A+A ultimate sprag $175 A+A Front Billet Steel drum $695 4 pinion planet with a steel spline front and rollerized $425 Red lined soild front Band $? Kevlar lined rear band $? Red Alto Clutches and Kolene Steels $? Teflon seals on front drum and input shaft $? Billet front and rear servos $180 Billet spring retainer for the front drum $45 CRT Low band apply reverse manual VB $275 4.2 Lever $35 HD front band strut $25 Modified stator support $90 Billet pump gears $175 I'm sure I missed something , I have to go thru the pile of receipts still

A bulletproof and cheap 727 is called a TH400
I doubt that you can't just pull one out of a pickup and throw it your race or hot street motor ...
People go to the TH400 because of the design , NOT the cost .

All my buddys are gm guys. None of them make the power that I have, and they all weigh less than me. I can tell you this... None of them have anywhere near the trouble free operation that my A&A built 727 had. My car=3700lb, 3.50 rear gear,8.85/155 best. Trans was freshened once in 5 years after a rear end failure. Cost is a factor, but at a certain level, both trans' will cost$$$

 I got a bunch of stuff from A and A and couldn't be happier with the service or the product. How much cheaper can a TH400 possibly be? You still have to beef it up, and then adapt it to the dodge motor. I spent around 1K for what I needed. Heavy duty clutches, billet drum, 16pin sprague, low band apply VB, ridged KD band etc.. etc..

It doesn't matter what make of trans it is really, most using high end parts end up costing the same. I have dealt with both John Cope and Rick Allison and was happy with both. Would deal with them again in the future for my next transmission build.

No one likes to burn money, but I guess the question becomes, how much are your feet worth? I've seen a 500 hp small block scatter a 727 like it was made of fine china. That was with a manual valve body, a basic rebuild kit, and an extremely knowledgable local builder. Sprague failure blew it right out the bottom. You could see into the case, and actually look at the steels and clutches that were left of the front drum(drum long gone.) Only blind luck it blew out the bottom, instead of up through the floor. I dimantled my own following the incident, to find I only had 2 of 12 oneway springs remaining in my own 727. I could have blown the same way at any time. All with less than 600 hp.

they are as strong if not stronger than a P/G out of the box. I have a stock P/G in my Duster using Alto clutches and a good band with a t brake. Over a few hundred passes and zero problems with 6000 + RPM launches.Took it down about 75 runs ago and only replaced a few clutches that show very minor wear and only did that because I had them sitting in the shop. Otherwise I would have buttoned it right back up. I am sure a 400 is just as durable. Cost is much cheaper than building a comparable 727.
You're beating that "Dead Horse" again Fred..  Happy B-Day..
I vote P/G too, but some don't get it or just don't want to hear it.. 
If you have to put a Torqueflite in it..Call these guys..

Well I stand corrected, but don't forget to add $300 - $500 for either the adaptor OR an ultrabell .
