I had this same idea, but was wanting to try a 5 speed out of a Fbody. the 4L60E out of a truck wont bolt up to a 3800, 3800s use a 60* bellhousing 4L60E from truck is 90*.
I was told the 4L60E will bolt up just fine...
the s10 with the 2200 will bolt any of their transmissions to a 3800.. Just need to make sure the flexplate spacing is correct.
