EDIT - wait you're using an NP203 or NP205?? Still in theory you should be able to do it but I just took out a TH350 for a 700R4. the Tcase was still the stock NP205. I also used the Advanced Adapter output shaft so I could mate the new trans to the OE Tcase.
Thanks for the feedback. It is a 203. The Blazer had a NOM 400 SBC and a TH350/NP203 in it when I got it. It was originally a 350/SM420 combo. If all goes well, we might be doing a test drive by Sunday evening.
