Yeah that's the thing with newer builds, lots of 1000 hp dyno queens. Take a look at the more serious HC/Demon guys and you'll see legit et's matching hp claims. The ingredients are there for a high HP NA build but no ones done it yet
Thats because most change over to turbos.. its easier
and a high HP NA G3 build would probably be the most expensive compared to all other Mopar engine platforms.
