I can't grasp why you would do it either unless you already need new pistons and liners. Then hopefully the pistons and liners are better than stock, which is not often the case.

That is a good question. I know Tim posted that the 3.6L lasts longer hours wise than the 3.8 and 4.0 options. OP do you know if the pistons are CP or something equivalent. I don't know much about the protomotive builds though.

I don't know about making more power at the same amount of boost

On the average, 3.8 will make 5% more power at the same boost level then a 3.6. Also you should be able to build a 3.8 L for the same price as building a 3.6 motor. I think if you're going to tear into the motor this is a cheap place to make more power. Remember that I am from Texas, our state motto is bigger is better!

i asked layinback this exact question when he did his... 40 more rwhp and better off boost response. nice upsides. 5000$ in parts plus labor big downside!! for my limited budget i couldn't see the hp vs dollar
