On 2.7s it seems the general consensus is somewhere between 450-500wtq is where the factory rods decide to say goodbye. I've also seen stock valvetrain 2.7s rev to 7500 rpm fairly consistently. Assuming you had the right fueling, and k24 or similarly sized turbos. Could you not maintain 400wtq from boost onset to 7500rpm with a rising boost curve and produce 550 whp on a stock long block 2.7?

Now I understand that I may be missing something obvious or maybe not so obvious but I'm prepared to get flamed a little bit. If I am wrong could it be explained so that me and the people reading this later could learn?

Oh wow, that's impressive. Out of curiosity what did the torque look like when it got dynoed? But that's totally fair, I mean stock cars can throw rods if they aren't maintained. I was just looking for a better sense of what is possible because it seems like a lot of cars stop around 450whp saying they are limited by rods which just didn't make a lot of sense to me.
