I’m looking at from the “it’s GM” filter, so you can toss the 4.5 out of the equation. I’d say the 6.3 AMG and 5.2 Voodoo are the best comparisons we have. Both make around 100 hp/l, so 550 is more than likely the high end. Given it’s GM, I wouldn’t be surprised to see them dial it back for reliability, putting it between 520 and 540 hp.
