Was the silverado donor 4WD? There may be different oil pans for 2 and 4 wheel drive applications. You might wind up having to modify the pan you have. Interesting project, keep us posted.

 

I can't imagine that a 2008 4.3 out of anything would fit a 1994 blazer without a lot of mods. I know for sure you would have to replace the wiring harness and computer.
