82 2wd Blazer from TH350 back to 700R4 INFO NEEDED

[erikgto]

Hi Guys,

It's been a while since I last posted here.
I've bought RDM1208's '82 Blazer 2wd (shown in the 2wd Blazer tread, it's the dark burgundy one with the '89 front and 20" wheels)
Right now I'm waiting for it to be delivered to me.

This Blazer came from the factory as a 305/700r4 unit.
The shop that customized it back in '96 put in a rebuilt seventies 350/350 combo.

What do I need to go back to using a 700r4 besides a transmission?
Can I use the torqueconverter that's in it now?
how about the cross-member.
Any other things I need to look at?
Would a 4l60e be an option or is that a bad idea? or an issue with the speedometer/cruise control connection.

Any other advice?

Thanks!

Erik
