Sorry I didn't respond sooner. I don't get online as much these days. Anyway, that question is hard for me to answer because I can't comment to the expense and value aspect as I just wanted to always do the LS4 swap. I didn't have any real budget or horsepower goal in mind. I simply wanted to do it to prove to myself that I could. If someone is going for straight power vs cost, it would probably be cheapest to turbo a 3800, and blow the LS4 away. But for me, yes, it was 'worth' it to just do it and have it work.
