Hello everyone ! I have recently purchased a used 700R4 ( '84 Monte I believe ) and plan to swap it out for the powerglide currently residing in my Impala.....for numerous reasons. This will be my first swap and would appreciate any knowledge available on this....web sites , past experiences , things to look for,etc. I am planning on having it rebuilt proffesionally and doing the rest myself.What is the going rate for a rebuild ? Will either torque coverter work ( rebuilt 327 /edlbck prfrmr intake & carb /msg billet hei / stock cam , heads , bottom end )?Planning on edlbck heads/cam and EFI within next couple years .Will that change converter and rebuild needs ?

Thanks in advance for any assistance / advice.
