Another 440 Intake Question

I don't think I'm going to dyno it. Usually cost to much for an engine dyno. I'm not even sure if there is an engine dyno near me. Most horsepower either of us have driven is his 2009 Challenger SRT 6.1L. And I know you can get in trouble quick with just 425 horsepower, hey but whats another 75 horsepower, lol.
