They charge $550 just for the shaft but I'm not sure if they will give that price just selling the shaft if that is what your asking.

Your result is very encouraging. I was leaning toward t56 conversion until I read your post. I also haven't broken my FD transmission yet with my 20b, but I never launch my car. I somehow thought PPF was part of culprit that twisted the box. I am using FD box with FC tail housing with transmission mounted to the frame instead. I have a spare FD box, I may have to give liberty a call soon!

The latest offering from PPG in Australia. The sequential T56.... 1000hp+ rating. Target price is around $18K as an assembled unit.
T56 Magnum is less than 1/6 the cost.... rated at 700hp.... in a 4500lb car launching on slicks without failure. These have been put in 1000rwhp cars without any real issues. They do weigh 135lbs. If you are interested in either item or rebuild parts/kits please email me. My username at hotmail dot com

Why aren't people building an adapter plate to go between the FD bellhousing and the t56 trans? Everything I see has the adapter plate between the engine and a GM or other bellhousing. I'm assuming the input shaft is the wrong length to work with the FD bellhousing??? What is the deal. Thanks for the help.

I think Howard was saying you need to machine .25 of an inch off the rear face of the bellhousing to move the input shaft further into the stock pilot bearing. That's on an auto FD bellhousing.

the FD 5 speed bellhousing positions the starter facing to the rear. the T56 is wider than the stock FD box and interferes. the auto FD bellhousing positions the starter towards the front and solves the problem.
creating another problem... you need an auto rear iron to match up.

I have 2 Liberty built transmissions, 1 face plated and 1 not. I twisted off 2 input shafts, twisted 2 diffferent cluster gears and just recently stipped the teeth off 3rd gear. Paul is a great guy to work with and has been very helpful. The guys running 9 sec 1/4 miles are not as reliable as I want to be. SKWORLD (Mike) had a Liberty also but is now swapping. I am going to different track events and breaking which is a bummer. I'm now considering a T56 for the reliability.

The difference is torque and not just hp. At 700hp,13b is gonna make less torque than 20b. That's why the stock tranny fails so much on that particular swap. The higher torque is what's bending the output shaft. Now on 13b applications, I think abuse is the main problem.

I think it is quite different. Regardless if the torque is the same at a given RPM at full boost, the way the torque comes on a 20b is drastically different. On a 20b, the torque is going to snap on hard which would stress components more then the same peak torque on a 13b where it takes a bit to get there. The 13b would always be a more gradual transition between power and have more give in the motor for load changes. Apples & oranges imo.

20b has more rotational mass.

I would realy like to see those pictures! I would like to see a working simple solution. I know Howard C and ironmdx and bewtew have a t56 in their car but the installations don't seem similar. Some of them have custom plates made for the mating of the tranny and the engine (I could be wrong) Is your Trany mated to a 20B or 13B? Sorry I don't know your setup. Is the location of the engine stock( if your setup is 20B)
Thank you!
