Dano, something to think about. I know you said you wanted to "Cheveroletize" it, but the Isuzu V-6 from the Impulse used the same bellhousing as the 1.8L that's in there. So did the 1.9L I-4 turbo from the Impulse and Imark. From what I remember, every Isuzu RWD engine and transmission were identical in the bellhousing bolt pattern so they were all interchangeable. That includes the Diesels.

Yes, a 2.8L or 4.3L Vortec from an S-10 would be sweet, but that would involve a whole lot of fabricating as far as engine mounts, radiator, wiring, transmission mounts, driveshaft, shifter location, etc. It might make up for the lack of "Chevrolet" by being so much easier to use the Isuzu stuff instead.

I know when I had my 79 4X4 (with a 74 2WD body on it) I ended up dropping in a (lightly breathed on) 1.9L I-4 and squeezing enough BHP out of it to howl the tires all the way into 3rd (with a topper on the back) and still get 19-21mpg out of it. And I drove it like I stole it wherever I went...
