Even cletus, who's been an ls fan Boi for years was impressed by the 5.0. They had a 2wd 5.0/10 speed with a supercharger that made somewhere around 900hp for a giveaway truck and liked it enough to get another 5.0 truck. This time it was a 4wd with a giant turbo that made over 1k who iirc.
Fwiw, our 2.7 is a hair under 120k with lots of different use including towing and has been great. We bought it at 25k and have only had a wiper switch and 2 trailer brake controllers go out (no idea whats up with that, but I'm thinking I'll just go aftermarket)
I had thought about trying to trade it in around 100k miles, for a newer one, but I think I'll just keep it for another 200k miles just to make the internet buthurt
