Actually I'm glad I went that route.. when I started this project I was a newbie mechanic and all I knew was from what I read.. I didnt have the knowledge to rip out an engine and fab crossmembers etc, so I got into the nuts and bolts of the body and frame.. and either way it required swapping stuff under the dash so it wasnt much more work. Now I have the confidence to work on every area of the truck, and a chance to update/replace everything on the other frame, so its even better in the long run. How many miles on your 2.6? this 2.8 has about 180,000 give or take a few (broken speedo drive gear) and its still running great, but it just makes sense to put in the 3.4 while I have the chance..
