416 stroker cam choice

If you use a cam that will produce 400 hp it will have a nice sounding idle but it wont ever sound like a HFT on 108 LSA with a bunch of exhaust duration. Instead, it will make lots of power, which in my opinion is the purpose of a good cam. with a 3.58 crank, 400-450 HP is pretty easy with good heads and matching cam. You will want Edelbrock AG EFI, M1 or Super Vic EFI intake although AG seems to be best choice. A stage one TB, Flash. Your price range will not b an issue if you already have headers.
