First off thanks for the add folks. Look forward to all the tips articles etc etc on here.
A little bit of background info on me. I'm 55 and been turning wrenches on vehicles all my life. Actuall worked at a GM dealership 30 years ago. Still do my own wrench turning today but alot has changed since then.
Regrettfully my 4.3 in my 97 Blazer took a dump. Lost oil pressure long enough for whatever reason now she got a Purdy good knock to it. I've located a 2000 or so model out of a pickup with only 87k miles on it to put in the Blazer. I've got a couple of questions for you gurus. Others than the usual sensor swap making sure I put in the year correct sensors is there anything else that needs be swapped.?
Of course I'm dropping in new clutch kit while doing this. Only makes sense to do it now. On the 97 model can the cat be deleted and if so does it create or set a code. It has 2 O2 sensors upstream. If I can should help on fuel mileage. Anything else I need to pay close attention to or do now? Thanks folks.

Cat can be deleted...but why would you...there are 4 O2 sensors. You can delete them, but same questions apply. Deleting all this stuff won't net you much mpg if any.....more than likely you'll be chasing gremlins.
