Simple is dbc....
Look for holley,LS3 ,or tbss manifolds...the work on square bodys...
Although the 4.8 can be made to produce big hp I think in the burb youd be happier with a 5.3......6.0s and 6.2s are $$$$
You can get a new harness for a couple hundred bucks...theres a thread here recently on it...

Thanks I was just thinking about the weight of the suburban, I drove a '16 gmc Sierra with the 4.8 loved the drive but compared to a '14 gmc van 6.0 it was really sluggish.

What are the years to avoid with ls engines? I'm looking on Craigslist for wrecked or possibly just bad transmission and the local junkyard.
Which the last time I went to the junkyard there was a guy who pulled 6.2 out of a caddy ahead of me in line, I know I heard $179 and he had accessories on it. No computer but not a bad price.
