Transmission change

[chevyuser]

Hi all,
What do I have to change on a Blazer to replace its Th 700/R4 with a Th 350 or a TH400?
For all I know, the 350 matches without changes, am i correct?
But what with the TH 400?
Thanks in advance, chevyuser

the 700 is about two inches longer than the 350, so you will need to move the transfer case crossmember up and maybe need to modify your driveshafts. Thats all i know
