Th400 Into 3rd Gen
Has anyone out there installed a TH400 in a 3rd gen?
Engine will remain in stock position.
Tips will be appreciated.

many people have done this
you will need a new crossmember, or modify your exisiting one
need to lengthen your driveshaft IIRC
and need to buy the torque arm mount kit from hurst, which may included the croessmember
you will also need a kickdown switch
not a very hard swap

Got one in mine 
I used the Spohn crossmember and torque arm and the stock 82 driveshaft but with a TH400 slip yoke. Haven't gotten a kick down deal, mainly because I just do it manualy. Here's a couple pictures of mine when the 305 was still in.

Thank you for your replies.
My trans has a flex plate shield and an aluminum trans shield.
Does any of this require "massaging" the floor?
Thanks again,
Bob
