I am getting ready to make the move to a TH400 in my Satellite.I asked in the past for a pic of the trans tunnel adjustment but never got it so if you have 1 please post it along with the trans cross member.I am going with an Utra bell because I don't want a mid plate if I can.TIA for your help!

What I can say is mine don't last so I am done with it so post info if you have it .TY! Why? There is absolutely no reason a 727 won't live with your combo. I agree a 400 is good. But at what cost? You don't need one. Doug

HI what is the advantage? I have had a 727 in my super/gas lebaron for sometime now gary
all parts are sold as is, all parts are considered used no warranties or returns paypal/check/money order, shipping is from zip 02891, buyer pays paypal fees 24% IRS 1099A plus 3% of part price, check/money order preferred site is not monitored 24/7 there might be a delay in response

Do you want to slow your car down with the heavier parts in the 400?

You don't need one. Doug IF YOU CANT KEEP A 727 TOGETHER WITH YOUR COMBO EITHER SOMEONE IS NOT BUILDING THEM RIGHT OR YOU ARE NOT SETTING UP YOUR TV CORRECTLY.

Thank you for the info.If you can say nore on adjusting the floor/tunnel I would appreciate it a lot. I had a 400 in an ebody. I get it the parts availability and converter selection is much better. The ultra bell is heavy and you really need to move the floor/firewall around a good bit for it all to fit nicely. I would also recommend an SFI case. Trying to put a shield on it would be a whole other issue. A blanket works pretty good. Headers are another concern, depending on what you have you may have top reengineer them to fit. The TTI stuff probably won't fit without a lot of work. What kind of power and what does your car weigh? I have to say I thought about putting a 400 in the 65 I am building and just didnlt want to do the work required and just couldn't justify the cost. I have had a 727 in a 3700# car running 9.90s for hundreds of passes with 0 issues and just a billet drum and bolt in sprag. It can be done but I see the 400 benefits as well. Sorry I don't have any pics to contribute but hopefully this gives you an idea of the challenges.

Thank you for the information! Basically I agree with the above you really need to cut the tunnel and make a new one at least to the mount. The mount is not too bad to make, the firewall opening needs to be bigger, the area from there back needs to be taller and wider basically back to the mount crossmember. The lines are on the right side and not the left side as well. All in all if this were a 1200HP 3400# car on a small tire where shake, and gear ratio become a problem I would spend the time. If it is a bracket deal I would do a glide much easier or build a 727 with better parts.

[quote=Clanton]What I can say is mine don't last so I am done with it so post info if you have it .TY! What parts have you failed? Who is building your transmission? My car has well over 400 runs on the current clutches and band. Correct me if I'm wrong, but I believe you run low 10's? How any passes have you made? 100 or less? Doug

Turbo400 is a good trans. Can be built to hold a lot of power pretty inexpensively. The same could be said for a properly built torqflite. The benefits of installing a 400 into a B body, are not... for most, worth the effort. I understand being soured on parts. But It seems that maybe you would be best off to step back, take a breath, and re-evaluate your choice of trans builder. I assure you you are not making enough power to need to walk away from a TF.

Did you get burnt out and frustrated with the 727 while you still had the blower on the car?? Even a slow heavy car is hard on the trans. with a roots style blower. IF anything is deficient in it the torque. fails them quickly. Even my 11-0 streetcar has taken out 3rd FOUR TIMES. Finally got it sorted out. IMO with the blower forget horsepower, worry about the torque.
Your car, your effort your money and choice. Hope you get it how you want it...👍
