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.

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
