I took the last 2yrs off running it n/a to think about it so ya I gave it time.

I ordered a Rossler stage 4 Rossler trans

....which makes me think of the 47/48 RE torqueflight based trans behind the hopped up Cummins ISB

Just curious Clanton, was it repeated failure of one component? ...or a few instances of breakage. I’d still say at the level your at our favorite dump truck trans should be able to handle the task at hand.

Sounds like your next step is getting a JY core and start mocking things up.

Are there adapter kits available? I know pretty much zero about this. I do find it interesting how long people have been putting glides behind Mopars and still read about parts fitment issues here and there.

Hopefully you’ll start a post on this endeavor, or keep adding to this one. Lord knows we need reading material these days.

So now you are broke LOL.🙊
ROSSLER builds good stuff.
Keep us posted on progress and results.👍👋

I am not broke but 4,700$ is a lot just for the trans.I had a goal in mind when I started this and I will keep at it as long as I can.

This is where MOPARTS gets tunnel vision...and why most MOPAR guys are slower than the Brand X guys....

Someone asked about fitting a T400 to a B body, hes looking for info, what needs to be done.
Instead of helping him, you guys are chastising him, telling him a 727 will work, and he don't need a 400 etc etc
here some facts....

THE aftermarket is geared towards....T400, not 727's
COnverters, parts etc are all cheaper and more readily available for this trans, because almost everyone out there is using it.
Don't let your feelings get in the way....lol

honestly, a Rossler t400 may be overkill, but guess what, it will be THE LAST TRANS HE EVER BUYS.....keep up with fluid changes and it will literally last forever. I have a Rossler T400 for over 10 years, and still going strong. I make 915 on motor and 4-500? of nitrous on top

Clanton, to put a T400 in an A body, I fabbed a crossmember between my frame connecters. On the original crossmember, the part that passes above the trans I cut that back for clearance and fabbed a 16 ga flat steel to box it back in. Depending on how much cage you have that may not be necessary.
Any more questions ask, I did not do anything to the trans tunnel itself other than trim the lip where the floor and the firewall meet.
Hope this helps

PS : You made a great choice for a trans/trans builder, good luck

Rossler is a fantastic trans great choice, I agree you won't ever need another trans. May I also suggest a PPP shifter it will make your life easier for sure. Share some pics as you go through the process.

Did you lower the engine in the chassis? I mocked a 400 up in my 66 Coronet with an Ultra bell and it was not going to fit without making the tunnel bigger. I couldn't lower the engine because of the oil pan and headers so I scrapped the idea and went with a 727 I just didn't want to get into that much work. I had a simialer situation with my 65 although the engine is further forward the firewall wasn;t so much the issue as the tunnel from there back. Again both were gen 3 hemi conversions and the pan and headers limited the amount I could lower the engine. Just curious what you did to get it to fit without cutting the tunnel up. Also I agree the 400 can be just as fast as a 727 expecially when you consider the gear ratio options with the 400. I had a 210 Rossler in the purple Challenger I bought from Steff that car would go crazy sometimes and that 210 Rossler really got it under control. Also for the nah sayers I tested with a 727 vs a 400 in that car..............the 400 was faster mainly because of gear ratio and the ability to control wheel speed vs the 2.47 low gear in the 727. I know the purests here will not like that but it is the truth.

I use a motor plate, I really cant say why, but it fits my trans tunnel no problem.?? It is an A body not a B ,
I was surprised myself that it fit pretty well .
Im computer illiterate, so if anyone wants pics …..text me your cell and what you want to see, I can text pics..LOL
my number is 914 417 1312

The th400 from the bell back is just an 8" tube so I will test fit a tube to check the depth how it fits.I have 1" all around my 727 front to back so I think I may get lucky and only have to flat the tunnel lip to the fire wall.Thank you so much for your info!

I agree the Rossler is a very nice piece. I don't care if its GM or Mopar. If you were starting wth nothing and making BIG power I see the logic. What I don't understand in this case is someone gave up at 30 passes with a trans that easily would've worked. By the time this is all said and done it'll be way over $5K. Now I don't know about everybody but spending $5K+ is a pretty big bite. Especially when what you already have would've easily worked. You tell me. How many low 10 second cars kill a 727 every 30 passes? My 727 has stranded me once in 7 years (635passes). Every pass 9.2x or better@3350 or more. It was an aftermarket part design failure which was easily corrected. My trans in my sons turbo car with a 727 using a brake at 3750lbs (9's at 136 -142) has only stranded once as well in over 5 years. Easy upgrade to fix it as well. Just my 2cents

I took some measurements off my friends th400[width,length,height from pan rail] and I will compare it to my spare 727.

Ohhhh my God, Chevy transmissions. What’s next ford 9 inch rearends. We can’t even get our guys to give up 50 years old technology and update their radiator FLEX hoses and screw clamps. Lmao. Hemi guys included.

I have 2 transmissions that I went through 3 rebuilds 2 on 1 and 1 on the other.Not just 1 trans 30 runs.Maybe that is not enough for you but it was me and here we are.just an fyi!

The 727 is wider than the th400 from bell to tail housing basicly.

I had forgot about you using the blower, power will find all the weak parts

I don't really post at all, but I have run a 400 transmission in my 68 charger for a couple of years.
I recently removed it only because the car went to fast for the 5 point bar in the car.
It really is not that big of a deal to make fit. If your car is tied by frame connectors like mine is,
we cut the transmission crossmember to the center of the mounting bolts on each side. Then drilled out the
spot welds and made our own crossmember from rectangular tubing. It will put he transmission down about 3 degrees
lower than stock, but I was able to correct it with wedges under the axle. We never cut the factory tunnel.
It really is a sweet setup. I never experienced any vibration on the street or at the track. It easily stood up to a 498 wedge with
440-1 heads, 12.3 compression and a big shot plate system. With a 3800 Continental converter and manual valve body it really
was a great combo. Leaving on the transbrake with the unit the 1st time scared me straight. It also got me kicked off of all the
local tracks I can go to.
I returned the car back to the original 4 speed because I'm sill
a mopar [censored] at heart. And because racing a full size b body takes a lot more money than I'm willing to spend on a car I'd rather
drive
Call me if you have any questions 626 675 0664 pst
BTW, I still have the complete setup soup to nuts including the driveshaft and oil cooler if you do not have one already sourced.

maybee hes like some of us that had 727 bomb go off,i still dont trust a 727 no matter who builds it

Simple answer. Aluminum drum.
