I have my 392 ordered, how much power will it make?

Oh yeah and about that statement "it's far worse to over carb and engine than to under carb it". I can't agree. I have installed carbs several times that according to everyone's calculator is too big (sometimes way-way too big) for the engine yet after I tune it they run just fine. Right now my Cuda is a great example. Mild built 360 (home ported iron heads, cam=234 at .050", headers and Air-gap intake) has a 850 Holley on it and runs fantastic. I installed it just to test the carb as I have plans on using it on my new 408 I'm building. I figured if there was anything wrong with it it's better to let something happen to the old engine than the new engine. Funny thing is it's the best running carb I've had on the 360 and I've tried several on it, 670 Holley Avenger, 750 Holley vac. sec, standard 750 Holley double pump, 750HP double pumper, 770 Holley Avenger, 625 Carter AVS, and now the 850 Holley. When I say it runs the best I mean it's the fastest and yet it has throttle response just as good as any of the others. It is worse on fuel mileage though.
