Yeah like Devin said, I very rarely see RSCB V8 trucks up here, and I work at a GM dealership. Ever since I owned my truck I've always wanted to swap for an V8 and finally did and never looked back! Took a long time since I lost my licence, so I took my time and slowly gathered parts and rebuilt the engine, then finally put it in. To be honest I forget what year my harness was, I'm pretty sure it was out of a 01 2wd Suburban, everything worked except the low oil level switch which I will splice a new connector on when I get around to it, I check my oil at least once a week so it's no big deal. Have bigger issues I need to worry about lol. Should have my updated Nelson tune within a week or two then hopefully some of my other issues will correct themselves. Have had it on the road for a few months and it runs pretty good, very strong. As long as my little tranny holds up for the rest of the year I'll be laughing. Gotta get a new Y-pipe as mine will not hold a weld where it's cracked, not sure what kind of steel they use but I've welded it 3 times now and it just will not hold.

If I had to do it over again, had the engine totally assembled, harness, mounts, all the parts sitting beside me I could easily hammer it out in a day. Yes it would have been a bit easier already being a V8 but hey, I like a challenge. I'd do either again.
