Tim,

I researched the exact same thing back when I had a 1968 GMC 1-ton. It was a 305, with a SM-420 behind it. I wanted to pull the V6, but the SBC had to go back in the "right" place to make the rest of the driveline line up (It was a dump with a PTO).
I will see if I can find my PM's about it, but going off of memory, you had to use small block mounts in the I-6 holes on the frame, and everything is suppose to go back. I never did it, I sold the truck instead.
Hope this helps, and if I find those PM's I will copy them to you.

Thanks!
BBB
