This topic comes up frequently, in fact here is a recent thread about going bigger TB on a NA 5.7.

Your post states n/a modded. Can you state what mods you have? Unless you are stroked and supercharged I would not even consider the Hellcat TB. If your mods are bolt on and you have a tune the standard Fastman TB on a 5.7 is plenty. if you have a cam, headers, after market intake or 6.4 intake, then maybe a Fastman true 84mm TB or other true 85mm. Bigger is not always better. My 2 cents.
