392 swap vs 340/416 build

I have a question for you. Would that 11 grand get that 416 to a reliable, every day driven, no issue 485 plus horsepower? Actually, that question is directed at the naysayers that can't move out of the 60's. I grew up with the old school big blocks and small blocks. Have huge respect, that's what got me and kept me in the hobby. And now my livelyhood. Go with the Hemi, you'll be so glad you did.
You make an excellant point. My current 340 runs awesome but the more I modify, the more side effects show up as well regarding drivability and temperament. Since I'm 90% street and 10% track that has been one of my biggest concerns. I finally get the performance but at what cost.

I will begin looking more into the entire build process of the 392 hemi/6 speed route. Other than ebay, does anyone have reputable sources that sell modern powertrains like this? I'm all ears and looking forward to this build
