I like the idea of the “all new” trans built with all the components designed for the rigors of drag racing.
So, budget allowing...... a TH400 or PG based combo would be my choice.

It’s about time you got here. Aren’t you retired like most of us old timers. Lol 😂

900 hp, 572 CID will have plenty of torque to get that car moving with a PG.
I highly recommend the aftermarket case (with bell). All the guts should be aftermarket at that level, so there is some choice of 1st gear ratio. Like a straight cut 1.80 gear set. And the Turbo style input shaft with matching converter.

Since breaking my 499, and working on building a 563, my Jerico would be a ticking time bomb. Starting from scratch, I wouldn’t even consider a 727. Either a TH400 or Glide. Why not start with an aftermarket case, and much better parts? Better options for gear sets. Options are endless. After weighing out all my options, I came to the best option available...

I ordered a Clutchless Liberty 4 Speed.

At least something is going in the right direction these days. That is great news and I am exited to see it! I have so many questions.

I see lots of worries about the 727. Mine runs stock input and output shafts, stock input hub, 3 pin planets. Though I did go to a steel front planet after stripping 2 in aprox 725 passes. It does have aluminum drums and a home modified sun shell. Stranded me 3 times in 9 years. 2 of those were me being to cheap to invest in a steel front planet. The other was an aftermarket aluminum front clutch carrier failure. Who knows how many passes it had. I traded for it used. It was easily repaired and is still in service. Not that there isnt a time and place for a TH400 or a glide. But my 727 has certainly served me well. Doesn't kill clutches or band either. So basically it has a good front drum, Super sprag (though it never hurt the stock one), steel front planet. Like I stated it has some other used aluminum stuff. Front clutch carrier and a rear drum. But neither of those do I consider stronger than stock.

Contact Pro Trans (661-940-7400and talk to Dave or Darren about a Pro Flyte (a well kept secret about one of ht best drag racing trans out their) for that car

The parts and cases, call them for more info please
The Proflyte is a all out drag racing tranny with multiple choices on the ratio and is suppose to be (I've never own one yet ) very easy to maintain at the races and change gear ratios at the track also
A good friend of mine ran one for years in a very fast PSCA 10.5 Outlaw car in SO CA , it wasn't a Mopar but it did end up with a Brad Andersen #8 billet blown Hemi motor in it

Is the Proflyte a SFI case? Or is it a remachined 727 case?

727 case. No one makes an SFI Torqueflite case at this time. Most Proflites are 727 cases with 904 internals amongst other rollerized components. Nothing different as far as regular 727 maintenance other than it probably has to be done more often. As far as the whole multiple ratio thing...A&A has a whole gamut of ratios available in their catalog. Being easy to change ratios at the track....no easier than a standard 727. ProTrans, A&A, Joel's on Joy, and A-1 amongst others all build their own version of a Proflite.

I can understand using something like that when it comes to Class racing, and a 727 case is required, but in a Bracket car, I see no reason it's a better option? How much does a trans like that cost? Seems like no one wants to say...
