So, I’m down the rabbit hole on this. My buddy has an ‘06 STS-V with the same engine as my V, but…. It’s rated for more horsepower. Has anyone sorted out the story? Was it a marketing thing? Component differences? Yesterday, I spoke with a Northstar engineer, but he’d left GM before the LC3 came about and didn’t have a good idea.
