th400 swap

[Turbo317]

Well i decided im gonna go with a 400, i got a few questions on what stays and whats needed,
Lose the kickdown.
I have a new trans mount for a 200, can i use this with the 400 just lengthen the hole on the crossmember? I need a yolk i know, do you really need to cut the drive shaft?? if so how much? What about the tranny lines??? will the stock flexplate line up with a th400 convertor??
1 more ? whats a good convertor, im going to summit tomorrow, id like to get one since ill be there.
thanks!

Cant quite remember the exact length that you will need to chop off the drive shaft, but I have heard there is possibly a shorter yolk that can be purchase and get away without cut the shaft. Might want to do a search on the yolk. You can use the stock flexplate. depending on the valvebody, you will have to route a vacuum line to the tranny for auto shifting purposes. The stall depends on the turbo that you are going to use. Overall a 400 is a very reliable tranny and you should have any issues with the install.
