We have been running a 727 in our car for 4 years running 7.60/7.70 2850# door car. 496 predator head engine spraying a 500HP shot of NOS off the start. The trans was built by Keith Long aka 727 Specialist. It has a Griner 2nd gear start valve body and mostly A&A and TCS parts inside with mods done by Keith. Took trans apart with over 80 passes and it showed very little wear on parts and clutches. We launch using 2nd gear (1.45 ratio) shift around 7800 thur lights at 8200. Have a 2.28 first gear but car likes coming out in 2nd. We have not had any problems except ripping 2 lugs off convertor had 8 mounting lugs install on convertor to beef it up. Convertor is a Transmission Specialties spragless convertor. Rick at A&A said we should be good to about 1600HP with what we have inside. We use only Sygnery synthetic fluid, trans temp never goes over 190*. We have had very good luck with our combo, Keith may be able answer questions too. Video of a pass. Good luck https://www.youtube.com/watch?v=_MR296wWfYg

If you go 400 call Rossler.He builds trannys for everything.If they last behind a pro mod Im sure he can build one for you.If you stay TF call John Cope at CRT trannys.Rocky

My GM one wire quit and all I had to do was take it to the alternator repair shop.
My Demon is in real trouble I suppose as it has a Ferd based rear end, GM alternator, and who knows where the 5 x 4 3/4 rear bolt pattern came from.
And did the repair shop tell you what was wrong with
your alt... like was it the reg

You certainly know what you are doing as you are doing it well but why not a glide with a 1.80 first gear?

So if starting from scratch how much cheaper is a full blown 400 vs 727 for a 1000rwhp 3400lb car converter and all?

If the cost was exactly the same, the 400 wins out for a few reasons. One, there are no aftermarket 727 cases, so that means a shield or a blanket is still required for those. Either of those is extra expense, weight and generally cumbersome.......Also MANY more gear combinations are available for the 400 than the 727......The converter distance in a 727 is shorter than a GM trans, meaning all the GOOD cores can't be used in the 727 without a spacer between block and case. This radically effects your converter choices, especially for higher HP applications. Lastly, there are WAY more really good parts available for the 400, which ultimately means that the BEST 400 will likely be cheaper than the BEST 727.

As usual opinions are like buttholes everyone has one,so Here's mine. Depending on the power level and the complete setup determine what transmission to consider.If you going to use it in a blowen application in a chassis car them you should consider Lencodrive or Brunodrive.I would not rule out the Rossler glide either but the OP eliminated it. The problem here is when someone reads these recommendations they think that for some reason they have to go to GM style trans in their 1000HP and under bracket car.If their goal is a low 9 second,3500 hemi bracket car there is no reason not to run a well built T/F with a shield and all the good parts.CRT,A&A,Turbo Action and others can provide all the necessary parts for a strong unit.Once you talk GM and add on all different parts like aftermarket cases the cost goes up.The GM application fits well in certain applications but for your basic hemi bracket car that is backhalved we recommend the trusted and proven T/F.We ran a mid 9 second Camero similar to the basic backhalved bracket car and found the T-400 a costly unit to maintain and repair. The focus needs to be put on each individual build and application and not one size fits all.Anything blown,turbocharged,or nitrous should have the best trans,strongest case,converter and parts for each of the intended application.We would never choose any stock case GM,Chrysler,Ford in any 1000+HP chassis type car especially in a blown application.  Just one more opinion

the car is going to be for a street strip set up not a race class car.(sort of bucket list thing) never the less he knows he needs a serious convertor.there is NO short cut,or cheap way of doing this.
1000+hp will find its weakest link,starting w/trans. its going in a 71 cuda,3500 lb car
