What would you do?

Here's my dilemma. I have the 68 stepside in my avatar and I recently purchased a two wheel drive Blazer. With the exception of the paint, wheels and interior panels, it is pretty original. The 68 is very customized and currently has an LS1/4l60E combo in it. As the Blazer is my daily driver, I am considering swapping the original 350 to the 68 and the LS1 to the Blazer for fun factor and mileage. I should be able to pull everything I need off each one and parts cost would be minimal. If you were in the same situation, what would you do? Thanks.
