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



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
