TH200c 3.8 to TH350 with 1977 Buick 350.

[MrSony]

Hey guys. On Friday, I am making quite a trek in Friday to get a 1977 Buick 350, minus the carb and Alternator, plus the accompanying TH350 . I was wondering, how hard would it be to do this swap? I was fulling planning on ditching the computer system entirely, so that shouldn't be an issue. I know many of you (cough cough Blake442) have done this swap countless times, but I ask of you, is it hard? What are some things I wanna look out for? Thanks.

It's REALLY easy!
V6 comes out, V8 goes in
Flip thru my thread again and you should have a good idea of what to watch for.
You'll probably want to take a little more time than I did and label and bag your fasteners and electrical plug-ins...
Taking lots of reference pictures helps too.

Do i need a different driveshaft? Or have it shortened?

No driveshaft mods. The th200c and the th350 are the same length.

And since the TH350 is opperated by vacuum, where would be a good place to tap into for enough vacuum?

Well, the normal shifting is anyway.
